Where do you find the firewall in a 91 chevy c1500? im looking to wire my subs but i cant find the fire wall, so i got amp wires running from the hood through the door into my cab.

The firewall is that whole area that is under the hood bellow the winshield and between the fenders. Its right behind the motor, you can't miss it. It seperates the engine compartment from the inside of the cab.

I have a 91 k1500 ext. cab 4x4 and my 4 wheel drive wont engage . what all could it be?

SOLINOID ON FRONT AXLE IS MOST COMMON PROBLEM. CHECK FOR POWER ON BLUE WIRE AT SOLINOID ON FRONT AXLE. KEY MUST BE ON WITH SHIFTER IN 4X4. CHECK FUSE FIRST I THINK IT IS THE SAME FUSE AS RADIO.

Check engine light on? Does it run normal driving it? Sounds like a vacuum leak. Check the gasket under the throttle body.

Four wheel won't engage

Theres a vacume dash pot under the battery box. It pulls a cable that engages the front diff. Put the vacume line and you'll have lights and four wheel drive. (it happened to my blazzer)
