Haltech harness routing???
 

I am installing my first Haltech on my 87FC. I was wondering if some people could post some pictures of how they routed there harness and were they mounted there MAP,TPS,RELAYS etc. Are thier any local Nor Cal folks that might be able to give me a show and tell of their engine bay if so that would be awsome.

don't be shy people...just looking for ideas...don't want to have to redo a mistake (measure twice cut once)

I didn't take pics, but I removed the stock wire harness, then ran the Haltech harness through the same hole in the firewall. (I mounted the Haltech in the same spot as the original ECU). I mounted the haltech fuse box, and the 2 relays on the passenger side fender. I think I put the MAP sensor on the firewall or the passenger side fender, I can't remember without looking. All the other stuff was plenty long enough to reach (fuel injectors, air temp and coolant temp sensors) I ran the grey wire for the CAS along the firewall, then down the driver side of the car to the CAS and coils. The power, ground and fuel pump power wires go down the passenger side, across the top of the radiator and to the battery. The other fuel pump wire comes inside the car behind the dash, and under the driver side of the dash to where the circuit opening relay is. I removed the relay and attached the haltech wire to the one on the stock harness where the relay was that sends power to the pump. If you are still using the stock AFM, do not remove this relay. If you attempt to use this same location for using the haltech to power the fuel pump, be sure you verify the wires in the Factory Service Manual (available online at www.iluvmyrx7.com or www.fc3s.org). If you attach the fuel pump wire to the wrong wire in the relay harness, you could send power to the started, which will constantly engage the starter instead of the fuel pump (ask me how I know:D). Another wire in the harness is live power, and connecting this to the haltech fuel pump wire will blow the 20amp fuse (ask me how I know:D)

Thats all I can think of right now. But from where I mounted the haltech and ran the wires, they were more than long enough to reach everything.

I drew up a general diagram, but I have no way to upload it easily right. :(

I try to keep the general positions of the stock sensors, so the Haltech MAP ends up with the stock FC boost sensor was in the passenger shock tower. Everything else is pretty straight-forward.

here's a link to some pics of my build up... hope that helps out.

thanks for all the input .i am still waiting for my fuel injectors and some other items before i start the install... i will continue to monitor the thread for new info...thanks again
