Hey guys,
I'm about to drop my 87 L98 into my 84 Z28, new fuel lines run, intank pump installed, have the engine harness waiting. My questions are, 1) Should I have the harness hooked up in the car already waiting for the engine or hook it to the engine 1st, then drop it in? 2) The car was originally a carb'ed car, using the engine harness and pcm from the 87' , is there anything I need to do besides connecting the two connectors at the firewall to make things work? Like fuse box stuff or anything like that? 3) I have aftermarket guages, no cel, or any of that stuff, will it take anything special to make my guages work? 4) Is there a wire I can tap into to make my own CEL? the original Diagnostic port still exists, I would love to tap into it and make the car as user friendly as possible. I figure going to a FI motor a CEL is probably better than just waiting for something to go wrong. Thanks in advance.
