starter relay and starter

[scroller bill]

Hi all. Have a question about my starter and starter relay. My vehicle info is in my signature.

On my bronco, the positive cabel goes from the battery to the starter solenoid(large terminal) then from the solenoid(other large terminal) to the starter. I got 2 wiring diagrams for my year bronco from 2 different sources, in that diagram the other large terminal on the solenoid goes to the ignition coil and throttle actuator. It shows a wire from the small terminal of the starter solenoid to the starter. Which is right, the diagram or my bronco? This confuses me.

Also is it true that wiring diagram wire colors may not match the actual wire color on the vehicle?

Thanks. Bill

Bill on your bronco you have a positive/red/hot wire going from your battery to one side of the starter relay ( 3/8 lug ) The other side of the starter relay goes right down to the starter lug on the starter motor . The little wire on the starter relay is the one that pulls the starter relay in or turns it on . If you notice the relay has a metal tab that mounts it to the fender well this is where the coil in the starter relay gets its ground/neutral/negative/common or whatever you want to call it . If you were to take that relay and put the metal tab against the negative post on the battery then run a jumper wire from the positive side to the little post on the relay it would click or pull in or turn on whatever you want to call it . When the solenoid pulls in it completes the connection between the cable going to the battery and the cable going to the starter there must be a good ground cable going from the battery negative to the motor block to complete the circuit for the starter motor to spin. Now the little wire going to the solenoid goes directly back to the neutral safety switch on the transmission and on a stick it goes to a switch on the clutch pedal that interupts the circuit so you cant roll the motor over without pushing in the clutch. From either of these safety switches it goes directly back to the ignition switch to a post on the switch that only has 12 volts on it in the crank position . So when you turn the key to crank position power goes through the wire to the neutral safety switch if in neutral it goes to the starter solenoid where the solenoid pulls in power then goes from the battery to the starter and the motor rolls over . Not sure how else to explain it . I believe the color of the wires for the neutral safety is red and a red with a white tracer . The other set is a black and a black with a purple tracer that one is for the backup lights so you will have those 4 wires coming out of the neutral safety switch . /emoticons/[email protected] 2x" width="20" height="20" />

Ditto on what Blade262us said. The other diagream is for later model Broncos.

Thanks guys. I know that I can go by what you say because you are very knolegable. Just wanted to say that the diagram I got said it was for a 85 bronco. But what you say about the diagram being for a later model bronco does make sence because the wire colors on the diagram do not match the wire colors on my eec wire harness. Thanks for all your help.
