2nd Gen RX7 ECU and Wiring Harness Question

[JoshS]

Pardon the rehash, but what is the common practice/enforcement here? I tend to agree with Jeff, but for a different reason. Replacement, without specifying a what constitutes a valid substitute part, implies that deletion is acceptable.

E.g.: "I am replacing certain wires and connectors in my harness with very very thin wires", or alternately "I am replacing them with air".

Thoughts?

You can't replace with air. So asssuming that the original harness has 50 wires in it, but your new one has only 25, you will be losing 25 wires. You can't do that.

The philosophy is that you can:
A) Add or replace both the TPS and its wiring
B) Add or replace both the MAP sensor and its wiring
C) Substitute worn, abraded, or otherwise undesirable wires and connectors in the original harness with new ones so that they are more desireable.

That's it. You can't gut the harness is the point. That also means that you can't remove the entire old harness and replace it with a new one unless all of the same wires going to all of the same places are in it.

It's been an accepted "interpretation" for a long time that you can replace bushings with air.

It's been an accepted "interpretation" for a long time that you can replace bushings with air.

Has that ever held up to a protest and appeal? I doubt it.

Ask any 1st Gen RX7 driver with a Trilink. Or search the board back during the debates over bushing material.

"Wires in the engine wiring harness may be modified or replaced."

That couldn't be clearer to me. Old harness out, new harness in.
