I'm trying to replace my factory cruise control switch with a simple toggle switch, which has two terminals on the back. I was assuming the back of the factory switch would be a simple on/off switch but that's not the case. Anyways I was wondering if there'd be any help out there with me doing this. I found a wiring diagram (located in 4(C-E 15), page 6 of the document) but I'm not too sure as to what wire I should be splicing the toggle into if this is even possible. Thanks in advance.

If I'm reading this diagram correctly, you need to connect the [BLK w/ YEL] (12v+) to the [YEL w/ BLK] (to cruise module) to each end of the switch. You may also need to connect the [BLK w/ YEL] (12v+) to the [RED] (also to cruise module), but I think that it needs to be done with a switching relay.

In other words:
[BLK w/ YEL] --> Pin 30 on 5-pin relay
[YEL w/ BLK] --> Pin 87 on 5-pin relay
[RED] --> Pin 87a on 5-pin relay
Fused 12v+IGN --> Pin 85 on 5-pin relay
Pin1 on toggle switch --> Pin 86 on 5-pin relay
Pin2 on toggle switch --> chassis ground

Once again I am not an electrical engineer, so try this at your own risk.

I thought of a better solution: use a 3-pin ON-ON switch. Bring power in to the center pin, connect RED to normally closed position and the BLK/YEL to normally open position.
