It sounds like you have some issues with your main ignition wiring. In your last post you seem to have some of the ignition wires coming from one harness and some from another. Here is what you should have connected: From Main (heavy gauge) ignition harness: Red, RED / White, RED / Black - connect together (before or after fuses.. doesn't matter as long as there is at least 1 fuse within the line somewhere) - Red 12v constant wire in vehicle Pink - Pink Ignition 1 wire in vehicle Pink/White - White Ignition 2 wire in vehicle Orange - Orange Accessory wire in vehicle Violet - Yellow Starter wire in vehicle *You will also need a relay connected as stated in my previous post to power the Brown 2nd Accessory wire in the vehicle From the Single Row Main Harness: Red - Connect to one of the red, RED / white, or RED / black wires. Or anywhere with a 12v constant signal. Just make sure it stays fused. White - Brown parking light wire in vehicle Black - Chassis ground (preferably low in the driver kick panel) From the small gauge multi-pin harness (possibly 18 pin) Brown - White brake wire in vehicle BLACK/ White - chassis ground Gray - Hood Pin Violet/White - white @ instrument cluster - Tach signal from vehicle (don't trust the DB-ALL signal) DB-ALL: Connections how you have listed are correct as far as I know Kenny

Thanks so much for the help. Ill give it a try. Just found out that the DBALL isn't flashed for my truck. Doing that first thing tomorrow and ill give this install a try. I'm sure something will go wrong and ill be back! Thanks again though. There is just not any really good directions out there.

How do I go about hooking up a relay to the Brown second accessory wire?

Just like this but substitute the (-)200ma 2nd ignition wire for the (-)200ma 2nd accessory wire. Kenny

Can someone verify for me if my diagram is correct. In my photobucket it is showing up properly (coil to 12v constant) but even if I refresh, it keeps showing up as the old diagram I had before fixing it where the coil was going to ground... I'm confused as hell right now.Kenny

That is so weird. Even still it is showing up on my screen as the (-)2nd ignition to one side of the coil and the other side of the coil to ground. I noticed the error when I originally posted it, then went back and edited it and then re-hosted it. Oh well. Glad its working for everyone else..hahaKenny

Still lost on this brown relay wire. What kind of relay do I need?

standard automotive relay . 30 or 40 amp will do.Ted

Got everything ready to install. Now on this relay part, Do I hook up the pink/white wire from main heavy guage wire or the pink/white wire from the 18pin connector? Same with the orange wire, From heavy guage or from 18pin?
