Hey guys. Well im changing bodies on my 94 chevy K1500 because it got rolled. I boaght a 94 chevy diesel with the same body to put on it for really cheap. Some problems im having, the wiring was all different and not i cant get it to start. It turns over but not getting any power to the coil and no spark to the plugs. Should i change the whole wiring harnes from my old one to this one? Another thing is i found the turbo that was off of the deisel pickup, is there any way i could mount that to my 5.7 gas engine or would it not work or will it cause the motor to fry. Anything guys please help.
