Dual H/u

[streetfighter]

Go to www.metraonline.com enter your car info, and it will list a bunch of adapters listed. Like the GMOS and GMRC-01.

Did it have one of those in it, and is it still there, or did you remove it?

Without the adapter there is no ignition, so they will run the red wire to the fuse box to get Ign sometimes.

If you have or can get a meter check the Wires for constant 12v on yellow, and 12v on red when key is on.

If those are good, you can double check the ground by grounding to a piece of metal in the dash.

If you check that you have power ign and ground, then its a bad H/U if the fuse in it is good.

Make sure you check for power and ground right at the connector for the H/U.

Sorry trying to cover several posts, so kinda jumping around here.

I think I may have found the culprit.. The yellow battery wire after digging through is a 15A and the fuse size in the back of the H/U is a 10A will I have to get I new fuse?

it should still turn on in that case. theres something else wrong

Yes, even if fuse size is different if you have power at the ylw, red, and good ground at the black, then the H/U is probably bad. Last check before taking it back would be Kranny's LFC. Unwire radio, hook up ylw and red to batt +, and Blk to Batt - . If it still wont come on its definiteley bad.

If it now comes on then start over at wires checking ground first.

I made a new discovery, after getting even more electrical tape off it appears he has the pink wire tied into the 12V red ACC. I feel like a kid in a candy store because of this tape lol.

Alright I put the red an yellow on positive and black on negative and nothing.. I feel bad now, but you never know.

Does it have an adapter in it or are you wiring directly to factory wires?

Here are the reported factory wire colors:(still always check with meter before hooking up anything)

Dont feel bad, i always check actually having a bad unit as last resort. It does happen but not that frequently.
