The ignition switch does not go to the starter solenoid . Pin 87 at the starter relay sends B+ voltage to the starter relay . Do you know what a starter relay is an how it works ? The ignition switch is an input to the PCM - engine computer . When the PCM sees this B+ voltage from the switch it energizes the starter relay sending B+ voltage to the starter solenoid . http://www.bbbind.com/free_tsb.html free wiring diagrams !

Two heavy gage red wires one from the battery the side goes to the starter . The other is red with a light blue stripe ( small gage wire) Goes to small terminal . Starter solenoid located on inner fender ,engine compartment , not on top of starter ?
You can go to www.bbbind.com/ for free wiring diagrams . On the home page click on technical information five box will come up . Click on tsb's an free wiring diagrams . On the next page go to bottom an click on I agree . Next page click wiring diagrams an then enter your vehicle make, model ,year , engine size.

At the top you can zoom in closer an on the sides click on the arrows to expand the diagram right an left . The first diagram if you look on the left side near the battery you will see the starter relay has three wires going to it. Good luck hope this helps >

if your just reconnecting the starter wires the terminals are different sizes and the wire eyelets are different sizes to match up with the terminals.

Some starter solenoids are mounted on the fender near the battery and some are on the starter itself.

Typically the ones mounted on the fender have two larger posts and one smaller post. For the larger posts: One connects strait to the positive post on the battery. The other connects strait to the starter. The smaller post connects to the neutral safety switch which connects to the start position of the ignition switch. Here is a diagram. Make sure the solenoid is grounded good.

For the solenoid that is mounted on the starter: Connect the positive post of the battery to the large post on the starter. Connect smaller neutral safety switch/ignition switch wire to the smaller post.


Here is a diagram if you have both solenoids

Don't forget to hook backup any other wires that were hooked to the positive side of battery/solenoid like alternator wire etc.

What exactly is the problem? Im an installer for Quality Auto Sound
