Me and my buds are doing an aftermarket deck install on a 91 Pontiac Firefly and need to know wire color info to hardwire it to the cars connector. We’ve looked all over the web and can’t find a thing! Called car audio shops and they all want money. Here are the colors to the wires; hopefully someone can help us out:

A: Solid Red
B: Solid Orange
C: White w/ Black Stripe
D: Red w/ Black Stripe
E: Orange w/ Black Stripe
F: Solid White
G: Red w/ Yellow Stripe
H: Solid Black #1
I: Grey w/ White Stripe
J: Green w/ White Stripe
K: Solid Black #2
L: Grey w/ Black Stripe
M: Green w/Black Stripe

This is our decks wire color info:

Ignition (+12v Switched) - Red

Nobody wants to work or give their knowledge out for free. Myself included, but here I am. It should require one of 2 harnesses.

Metra Part # 70-1782 | Geo wire harness | Isuzu wire harness | Metra Online

Metra Part # 70-7991 | Suzuki wire harness | Metra Online

compare the plugs and you should be able to figure out which one it is. Buy one of these kits from a car audio shop so you dont have to mess with the factory wiring.
