You can zip tie them on the fuel rail....that would be the best way to mount them other than just letting them hang there.

 

I've seen that done but, still waiting for pictures of them mounted

 

why not find a place in the cabin. placing them closer to the ecu would keep them out of the heat and you could easily find a place to mount them. . . or 3m double-sticky-foam them to something.

 

I don't feel like sorting through ecu wires If they ever go bad, I'd like for them to be accessed easily

 

that would be easy to do with a multimeter and some extra wire, just place one end on the side coming out of the harness, turn it to ohms and just keep checkin wires at the ecu till you found the one with resistance (fool proof way) then splice the resistor in there.

 

I know, that's called sorting through ecu wires It's too cold in the garage to be on my knees

 

While we are on this topic. I have a pair of never used good resistors that came in my rx7.com fuel kit. They are for the 1600's 2nds.I am running microtech and you dont need them. Anybody need these? They are TMC-25 3 ohm 1%. Pm me..
