Hi ppl, I need a pm6 (crx si ecu) wiring hardness... My question is, does the crx DX or HF models have the same hardness ???

I mean, the plug that gets connected to it is it the same from the DX or HF ECU as the CRX SI (pm6) ECU ????

plz let me know

I just put a PM6 ECU in my 91 Civic Std.

It plugs in exactly the same as the old one...

The connections are all the same.

Yea i gotta question too....wat if i chip out a 90-91 integra ecu....the pr4 and run it in my 91 si?.....good idea?......chip it with that chip u find on ebay....the JUN one...cuz i dont want to destroy my SI ecu..so yea...any inputs?.

Hardness of both harnesses is about the same, all depends on how much oil was spilled on the harness, how long ago, and the operating temperatures. In hotter climates harnesses are harder.

Neither SI or DX or HF harnesses are not interexchangeable though.
Even though HF one might look just like an SI, it still isn't.

richboi - U ind33d can do that..... u mite loos ur A/C, but otherweiss it wi11 work. And wo cares about A/C, rite?

pakipr - another thing is that 89-91 SI harnesses are pretty much the same, but 88 is different in the area of driverside shock tower connector (88 plug is rectangular and 89-91 is round).

Just so you know what to check to get the right one.

Also - I was talking about engine harnesses.
If you meant the interior harness, then I can't tell you for sure, but most likely it's just like the engine harnesses - 88 and 89-91.

Tippyman - Plugging an SI ECU into DX/STD harness without harness modification won't take you far.

I'm on the roll today, aren't I.
