You should only need the main charge wire and a trip wire to start it charging, cap the others.

Installing 85 Iroc 305 into 57 Chevy; need wiring diagram to create EFI harness from car harness


Check out faxonautoliterature.com. They have an assortment of literature that should be able to get you up and running. There are original GM dealer service manuals for both vehicles which would have complete wiring diagrams. They list a separate wiring diagram book for the Camero. They have 2 different books on swapping newer GM engines into older GM vehicles. I've used them before and had excellent service. Hope this helps.

How do i replace the alternator?


REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable.
  2. If equipped with a pulley cover shield, remove the shield at this time.
  3. Loosen the alternator pivot bolt. Remove the adjustment arm to alternator bolt. Pivot the alternator to gain slack in the drive belt and remove the belt.
  4. Disconnect and label (for correct installation) the alternator wiring. NOTE: Some models use a push-on wiring connector on the field and stator connections. Pull or push straight when removing or installing, or damage to the connectors may occur.
  5. Remove the pivot bolt and the alternator. Fig. 1: Alternator harness connections 86753014.gif
    Fig. 2: Remove and set aside the alternator belt 86753300.jpg
    Fig. 3: Remove the alternator pivot bolt 86753301.jpg
    Fig. 4: Tag and disconnect the wiring harness connector 86753302.jpg
    Fig. 5: Remove the alternator when it is completely detached 86753303.jpg
    To install:
  6. Position the alternator assembly onto the vehicle. Install the alternator pivot and adjuster arm bolts, but do not tighten them at this time.
  7. Install the alternator drive belt and adjust the drive belt tension.
  8. Once the proper belt tension is reached, tighten the adjuster bolt to 24–40 ft. lbs. (33–54 Nm) and the pivot bolt to 40–50 ft. lbs. (54–67 Nm).
  9. Reconnect the alternator wiring.
  10. Install the pulley shield, if equipped.
  11. Connect the negative battery cable.

How to install 03 ford focus alternator?


Removing the Alternator
Disconnect battery ground cable
Remove the ground wire (black) from the alternator
Disconnect the positive wire (red wire held on by a retaining nut) from the back of the alternator
Now disconnect the wire harness from the alternator
Remove the drive belt
NOTE: Some models use a belt tensioner that applies tension to the drive belt.
The best tool to use for this job is the serpentine belt too.
If you can borrow one from a neighbour you can get one at PartSource. (Part# 648451)
On other models you will have to loosen the adjusting bolt on the alternator bracket.
If you're not sure about how to remove the drive belt, visit your local PartSource for free print outs of vehicle specific instructions.
Take off the mounting bolts from the alternator bracket
Now remove the alternator from the engine compartment There. You've removed the alternator. How easy was that?
Installing Your New Alternator
Put the alternator in the engine compartment
Install the mounting bolts that connect the alternator to the alternator bracket
Connect the alternator wiring harness
Now connect the positive wire to the alternator
NOTE: Your new alternator should come with a retaining nut.
Remember to remove the nut before you install the positive wire.
If it doesn't keep the old nut.
Connect the ground wire to the alternator
Now install the drive belt
This is a great time to replace your old worn out belt. When inspecting your old belt look for signs of cracking, oil soaked, hard glazed, splitting or fraying.
All these signs mean it's time you replaced your drive belt.
If your vehicle no longer has the belt routing diagram under the hood, visit your local PartSource for a free print out of the belt routing diagram.
Reconnect the ground battery cable .

Blower fan only works on high speed


Its the blower resistor. I couldn't get the pictures in sorry. Rob

RESISTOR-BLOWER MOTOR
DESCRIPTION
The blower motor resistor is mounted to the HVAC air
inlet housing, directly behind the glove box. The
blower motor resistor consists of a molded plastic
mounting plate (1) with an integral wire connector
receptacle (2). Concealed behind the mounting plate
are coiled resistor wires contained within a ceramic
heat sink (3). The blower motor resistor is accessed
for service by removing the glove box from the instrument
panel.
The blower motor resistor is accessed for service by
removing the glove box from the instrument panel.
OPERATION
The blower motor resistor is connected to the vehicle electrical system through a dedicated wire lead and connector
of the HVAC wire harness. The blower motor resistor has multiple resistor wires, each of which will reduce the
current flow through the blower motor to change the blower motor speed.
The blower motor control in the MTC heating-A/C system directs the ground path for the blower motor through the
correct resistor wire to obtain the selected speed. With the blower motor control in the lowest speed position, the
ground path for the blower motor is applied through all of the resistor wires. Each higher speed selected with the
blower motor control applies the blower motor ground path through fewer of the resistor wires, increasing the blower
motor speed.
The blower motor resistor cannot be adjusted or repaired and, if faulty or damaged (such as a cracked ceramic heat
sink), it must be replaced.

DIAGNOSIS AND TESTING
BLOWER MOTOR RESISTOR
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deployment and possible personal injury or
death.
NOTE: For circuit descriptions and diagrams, refer to the appropriate wiring information. The wiring information
includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness
routing and retention, as well as pin-out and location views for the various wire harness connectors,
splices and grounds.
1. Disconnect and isolate the negative battery cable.
2. Disconnect the wire harness connector from the blower motor resistor (Refer to 24 - HEATING & AIR CONDITIONING/
CONTROLS/RESISTOR-BLOWER MOTOR - REMOVAL).
24 - 138 CONTROLS ND
3. Using an ohmmeter, check for continuity between all of the blower motor resistor terminals. In each case there
should be continuity. If OK, repair the wire harness circuits between the blower motor switch and the blower
motor resistor or blower motor as required. If not OK, replace the faulty blower motor resistor.
REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deployment and possible personal injury or
death.
WARNING: The blower motor resistor may get very hot during normal operation. If the blower motor was
turned on prior to servicing the blower motor resistor, wait five minutes to allow the resistor to cool before
performing diagnosis or service. Failure to take this precaution can result in personal injury or death.
1. Disconnect and isolate the negative battery cable.
2. Remove the glove box (Refer to 23 - BODY/INSTRUMENT
PANEL/GLOVE BOX - REMOVAL).
3. Disengage the wire harness connector locking tab
and disconnect the wire harness connector (1) from
the blower motor resistor (2).
4. Remove the two screws (3) that secure the blower
motor resistor to the HVAC housing (4).
5. Remove the blower motor resistor from the HVAC
housing.
INSTALLATION
1. Position the blower motor resistor (2) into the
HVAC housing (4).
2. Install the two screws (3) that secure the blower
motor resistor to the HVAC housing. Tighten the
screws to 2 N·m (17 in. lbs.).
3. Connect the wire harness connector (1) to the
blower motor resistor and engage the wire harness
connector locking tab.
4. Install the glove box (Refer to 23 - BODY/INSTRUMENT
PANEL/GLOVE BOX - INSTALLATION).
5. Reconnect the negative battery cable.
