The switch wire would most likely fire the relay to power all the pink leads going to the PCM.
Yeah, do the 8 gauge since the fans seem to be powered by that fuse block.
About all you have to use from the original harness is the switched power wire from the keyswitch and the purple starter lead. The rest can go away except a/c leads if you have them. Oh yeah, save the oil pressure, water temp and alternator leads, too.

OK so keep the switch wire from the truck and connect it too the 12v sw on the harness but the purple starter wire from the truck goes where??Originally Posted by RedHeartbeat
this might seam retarted BUT!! "Oh yeah, save the oil pressure, water temp and alternator leads, too" where do i hook these up are these on the modded harness !!
sorry for all the questions!!!
The problem with small time harness builders is they leave so much to be desired.
Large gauge purple wire from the truck goes to the starter solenoid.
You'll need a water temp sensor from your stock engine. You can put an adapter in the passenger side head at the rear, there is a plug capping off the hole similar to the drivers side location.
You'll need an oil pressure gauge from the original engine. There is an oil return cover bolted to the driver side of the oil pan and it can be tapped to install the oil pressure sending unit.
The alternator lead can be tied into the small gauge wire on the alternator if its just one small gauge lead on the connector. Are there two connectors going to your alternator? Is there a large gauge wire going to the alternator from a battery source? There should be. If you don't have one you'll have to get something.
Do I need to drive over there and install that thing?
