I'm currently running a Holley and no emmissions. This means that the majority of the wires on the wiring harness are unused and are now stored on the passenger side (tie wrapped up and out of the way). I was thinking of getting my hands on another wiring harness and removing the wires that are not needed so that I don't have the mess on the passenger side that I do now. Can I just clip the wires off the new harness or do I have to do something special to make sure they don't short circuit or send a false reading to sensors?

Thanks in advance.

 

Just grab the 2 passenger harnesses and un-unpin whatever you dont need, trim the lenght and re-solder. You need:
Alternator wire (one wire per harness)
Oil pressure
Water Temp

I dont use the oil pan sensors.

 

what's the oil pan sensor for? Low oil level? Sorry if i sound stupid

 

im pretty sure its the low oil level. speaking of which mine came on and then went off last night checked it and added some and everything looked fine ....odd i have no idea what it was.

 

GREMLINS RX-7s tend to have a host of them living in their underbelly

 

I sat down with the FSM and depinned the wires I didn't need. The manual shows how to do it. Thee are 2 sensors on the oil pan, sub-zero temp sensor, you don't need, I'd keep the low oil sensor.

 

By depinning, you mean I can just remove them from the main connector? I'll check out the FSM.

 

i did this to a spare harness from a junkyard motor (just in case i kept the stock harness untouched), it makes the engine bay much cleaner

 

lol, the sa's dont even have a hole through the firewall on the pass side.
= no wires.

 

neither does my FB...it's routed around the front of the car along the crossmember to the passenger side.

 

That is correct.

 

That's exactly what I'll do. Thanks for the picture too! Did you keep anything except the water temp, oil pressure and alternator wiring?

 

Keep in mind that appears to be a 2nd gen fusebox.

 

If I have time today, I will take pix of my engine bay for "show and tell."

 

the harness i depinned still has all the block sensors and alt. wires, emmision and carb. wires are removed

 

 

hey wacky, what fitting did you use for your filler cap vent?

 

Fitting? 3/8 maybe?
