New Radio, how to wire

[LVJJJ]

Thanks to some folks on here, I discovered there is a kit to replace the radio pod and the cassette and controls. Got it ordered. Once I get it I'll find out what size radio I can buy. Sooooo, what am I going to find behind the radio and cassette for speaker wires???

Depending on the year of your truck, buy the plug and play harness that will match the aftermarket radio. But here is the color wires for the aftermarket side of things.

The easy way is to look at "Metra" and "Scoche (?)" For the adapter kit. One side made for the factory wire harness plug, the other side plugs into new radio aftermarket unit. New radio units are mostly "DIN" , meaning standardized sizes and wiring plugs. Single din, double din and soforth.

I learned on our 97 cclbd that the radio connector on the truck side is the same exact connector as on our 2002 avalanche. I took the double din out of the avalanche and put it in our dually. Took the oem radio from the dually and plugged it in to the avalanche. And the sliding locks on the sides of the radio were identical too. So it locked right in the factory spot.

Yes, GM radios were pretty much the same size and wiring connector from '95 to '05

Yes, radio upgrades in the 93 GMC, 95 Chevy, and the 98 Tahoe. The diff' between 93 to 95.!

Thanx all. However a new question. Found the Metra adaptor but it says it won't work if you have a factory amplifier. How do I know if I have one?

For the Suburban in your profile pic? If it's the 4 speaker system (1992-1994 dash and rear cargo area, 1995-up front doors and rear cargo area), you don't have the amp. If you have speakers in your rear passenger doors... you probably have the extra amp; it should be under the driver seat.

FYI if you do have the factory amp it will still work with the adapter harnesses. You just need to make sure to connect the remote wire from the harness to the turn on signal wire for the factory amp. IIRC both are blue but it's been a while.

Well I don’t know about the 400s but I do know I had to bypass the factory amp in my 2002 avalanche.
