Ok.. Ill start by saying it may be just in my head but it seems like my (92. 5.0 5 speed) idles slightly higher now. For the swap. I... Used 94 v6 alt, Used the premade harness from eBay . Ran a 4g fused power wire from the alt to the solenoid. Ran a 4g ground wire from the ground by the battery that the computer uses and ran it to front of block. The only thing I didn't do was run a new one at the rear to the firewall ( original is in place) Like I said.. It may be in my head but it felt different... Thoughts?
