Ok, I installed a new Pionner head unit in my EVO VIII. I got the unit from Crutchfield.com and I bought the wire harness so I would not have to splice the wires. But when I put the new HU in it works great but my stock sport gauges won't light up and the only one that works is my boost gauge. I can't seem to find how to plug the sport gauge wires back into the new harness........am I missing something here or what?????DO I need an additional harness????
Any help would be great!!!!!

 

where are you gauge harnesses splice into? if nothing works, resplice it into the dimmer switch. Green wire.

 

Sounds like you either hooked your ground to an illum wire on harness or twisted the two together or plain out left them hanging if your radio didnt have them. Pull your radio back out, your cutchfield harness will have 1,2, or 3 of the following. Orange, Orange/white, Orange/black. The plain orange is usually illum which I dont think off hand its in our evo radio harness, orange/white is dimmer which voltage adjust accordingly with your dimmer switch and orange/black is the same thing only it has a ground that varies instead of 12v. Make sure that you only have the orange/white or the orange hooked to the orange on your pioneer. If your radio doenst have a illum input which most aftermarket radios dont until you get at least 3/4 into the higher line radios cap or tape these 1/2/or 3 wires SEPRATE. The mitsu harness does not have a ground so im hoping you didnt hook the ground "black wire on radio" to that orange with black. It needs to be grounded to any chassis behind radio. You will have a blown dimmer fuse in your fusebox if you did anything wrong with any of these three wires. Just replace it and make sure you cap off all extra wires on harness. If you need anymore help, just msg me and I can walk you through diag the problem via aim or msn. Hope this helps. People come in our shop all the time doing their radio in mitsus and since they dont have a ground in harness, they ususally hook it up to the wrong wire. Like the black with yellow factory wire in harness is NOT a true ground and will cause problems if used.

 

hmm just read that is your gauges under your radio. I havent worked on an evo with the stock gauges, but I can still walk you through diag'n it. Gimme a holla if you need help.
