ANSWER
What do you need to know about the coil ignition wires? we can't help unless we know what the problem is lol be just a little more specific
the horn relay switch is in the fuse panel or it should be on the horn wires itself
No, none
The high idle may be caused by old spark plugs and wires. As far as the temperature problem there are several things that may cause this, but the thermostat is the easiest and cheapest thing to check.
The starter is in front of the engine, fairly centered, and easiest to get to from underneath the car. It and the solenoid are a pair of cylinders with wires hooked to them.
Follow the spark plug wires to the rear of the engine and you will find the coil packs.
it is located at the front of the engine under the coil packs(where the spark plug wires all connect)
Could be in need of a tune up. Start with replacing the spark plugs and spark plug wires.
On the front of the engine under the two ignition coils, follow the plug wires and under the coils is the ignition module. Changed mine twice . Works better now.
Check the fuses. If the fog lights are not factory original, someone may have overloaded a circut by adding them incorrectly. any frayed or broken wiring may need repair. try following the wires.
If it is the same or similar to an 87, there are a few small bolts holding the motor in place in its duct on the firewall (on the engine side), near the passenger side of the vehicle. Depending on the engine, getting it out may be a little difficult. There are also wires attached to terminals on the motor that must be removed by gently pulling them off.
I think the only way to get to it is to go inside the trunk. You will see the wires going up to it. Then after you losen it then you go back in side the car to change it.
I can help you I had that problem on my 1988 cutlass ciera and the answer is that one of the lights on the back not the third small on is not working. Open the trunk take out the bulb itself and check the wiring. That what was wrong with mine someone didn't have it wired right. Hope this helps you out.
