Truck harness layout Has anyone used a truck harness with a car intake on their build? I am using one and the way it lays out on my engine looks awful. 
Is there a way to make it look good? If so does anyone have any pics?

I already bought car style pigtails and soldiered them on the harness. The engine runs with the harness. I just wish I could get it to look better using the truck harness.

At bare minimum, the INJ connectors need to be swapped. To do it right, you need to go deeper

I generally retain the truck PCM location mounted behind the drivers headlight. Mount relays and fuses next to the PCM. Then re-reroute the Crank Position Sensor wires and pass O2 to go over the engine on the drvr intake side of the engine and shorten the O2 sensor wires. I have one trunk from the PCM to the DRVR intake side (inj, coil, TPS, IAC ECT, etc) and then down to the trans. At the rear of the intake, I add the OBD2 port and CEL (extended wires) to the engine compartment. From the rear of the intake, I have the passenger injector/coil power going back toward the front of the pass side intake . Makes for a pretty clean install.

I mounted my PCM on the inside on the firewall, so all of the wires feed back to it. For now I just have it wired up so it runs, and haven't really "cleaned up the wiring yet. I have a small fuse block mounted on the radiator core support, and those wires run in between the inner and outer fenders, then through the firewall also.
When I get it all cleaned up, the wiring should be pretty hidden.

I had to change from the truck brackets to ones from kwik performance so this picture isnt the most current but the best I have for now.

I found mine in a yard from a 3800 V6 car. I just cut them off and added them (solder / heat shrink tubing) to my harness.
I used a truck harness on my car but it took a lot of work to make it lay out decent. I have it at a point where I will open the hood and show people but it still isn't "factory" looking just yet.
