How do I connect the EPS on my 2012 Ford Fiesta to a Haltech system please

First it should have come with instructions. Second, why would you even mess with steering?

(I.E.-schematic for headlights,ecu,radio,etc)What part on the car are you trying to fix,do you need a chassis wiring schematic or engine wiring schematic??

I need diagram to the relays.

that is the ECU is bad, or fuel pump shorted.
there is a page that shows how to fix the MAD ECU box.
id say its not ecu, but there is a short some where.
96 ECU never fail.

my guess is shorted 02 oxy sensor or its wires melted against
the exhuast, shorting the ECU power to same.

No spark, only.
crank engine for 5 seconds. with scan tool connnected
release key and bingo, DTC tells you why.
bad cmp, ckp, or rpm dead.?

easy finds
unplug O2 sensor plug conn. at fire wall.
no fix clicking, ?
then at left rear tail , behind it, is huge conn. with huge pink wire.
pink is pump. pull connector, fix buzz? bingo shorted pump.
the pump can short partially and cause the ECU to go nuts.
the pump normal draw is 4 amps not 14..
a new filter for the pump , in front of tank , makes pump last 10x longer.
the full 96 EFI schematic is here. see all paths

see left, middle right links here.

Need schematic wiring diagram for 2002 Toyota Caldina

This is an (almost) impossible task. The immobiliser ECU which reads the key communicates with, and is controlled by, the engine ECU.
It's not possible to just "bypass" the system.
I said "almost" impossible because with the right tools, knowledge and unlimited time it may be possible to capture the code of a useable system, then design and build a black box to respond correctly to the engine ECU, which would allow engine operation.
If you have lost your only usable key, you need to order a new one (as you haven't indicated your exact model, I can't give you the correct part number - keys are different depending on model/engine).
You will also need a dealer who can programme a new key to your existing vehicle.
If your existing vehicle has problems with the immobiliser, you may be able to find a Toyota dealer to interrogate your OBD to see what the issue is. If not, replace the key transponder unit, then the ECU.
I've assumed you know it's an immobiliser issue, and that you've done the usual wiring and fuse checks etc.

Dodge stealth cranks no spark no check engine light. has fuel getting delivered to engine. checked all fuses all good. Ecu is good

Thanks for choosing FixYa and welcome to the site. There are a few things that you need to test and check. You need to check your plugs/coils, wires, distributor, coil packs, cam sensor and crank sensor. Check your timing belt/chain. Since there is no check engine light, you go in blind and you will have to check and test these parts, which some can be difficult. To perform the test, you will need a wiring schematic to test to see if any wires are without power. You will need to test these while the car is cranking. Check all electrical connectors and make sure all ground wires are grounded right. You need to check the wiring going from the parts listed to the ECU as well. You may be better off having your vehicle put on a diagnostic machine to pinpoint the cause. In most cases, it is electrical rather then the actual part.

No power going to the fuel pump... 1994 toyota corolla

4afe or 7aFE engine?
as always for ever and ever, check all fuses.
check it cranking some ECU dont power pump until cranked.
the ones that key on power are 3second, can you run that fast?
no. so crank.
if the fuel pump relay closing and sending full 12vdc to pump wire.?
then fuse is blown
if cel lamp is not on key on fuses, are blown or lamp or ecu bad.
fix lamp first it must glow, that glowing means ECU passes, basic self tests. (like a pc doing P.O.S.T) (i rebuild and tune ECU's)
do you need a schematic,( has it)

books are amazing things, no? im looking here, seen it many times.
the magic fuel pump relay on the 4AFE.
it is really a 2 coil relay forming what is called logic "AND"gate
7a works same,.... just looked
the ECU enables coil A with LC command line (software) 0v here.
the main relay must close and 12vdc out to pump relay
then the driver cranks, and relay coil B is activated. and pump spins.
always crank and test. see why?
if you need bigger photo ask, .....
if the relay fails to close cranked, check that the crank
signal makes it to (12v) to top left coil below.
if not there will NEVER be fuel. see crank sig below in red.

My Porsche won't start. I've changed all 12 spark plugs (it has twin plug heads), and am getting plenty of fuel into the cylinders (plugs came out wet), but still can't get it to fire. It has a Haltech ECU...

Pull one plug out of one cylinder, and place the top of the spark plug on the body of the car(grounded). Start(or have someone turn the car over) and hold the plug to a grounded spot. If the plug sparks it is not an electrical problem. Also, if the plugs are coming out wet, your flooding the engine making start even harder. Also make sure the plugs are gapped to manufacturer's spec.
