hey guys,
finally got pretty much all the parts for my det swap on my 97 180sx sr20de.
one slight problem though.. looks like my wiring harness is not plugging into my power fc.
the pfc is for a s14 and the harness looks like its off a s14a (ecu plug on harness is smaller than the pfc)
not to sure what to do. can i use a s14 harness with s14a injectors, coil packs etc..
other option would be to swap my powerfc with someone who has a s14a one

will i have to deal with the dreaded nats2 setup (hope not) ??
what will be different now if i go down the s14a road
anyway lads any help is welcome . Mr. Bennett where are ya

cheers

Have a look HERE..... There are loads to choose from for the S13/S14, and I couldn't tell you which one you need.

What wiring loom are you using?

John Bennett · 22-08-2006, 00:50

Here's diagrams of the two connectors. The bank of pins above 100 are the larger ones.

As Papa asks, what car did you get your SR20 and harness out of?

If you've got an S14 PowerFC, then you can get an S14 harness and it should fit the S14a Sr20 engine fine.
Perhaps exchange it for an S14a one instead, though?

NATS is not an issue with the PowerFC in any way

(consider it gone).

hey john thanks for the info.
gonna try and swap my pfc for a s14a one. if there is anyone who wants to swap just pm me. or if anyone has a old s14 harness that i can cut the ecu plug off please pm

i bought it off ebay from rhdjapan. ill see if they will send out a replacement for me.
so in the meantime if anyone wants to swap a brand new never used in the box s14 powerfc for a s14a one please pm me.
thanks again everyone

Mate, if you're going to keep the PFC, use the entire S14 main engine harness, not just the ECU plug

. It should plug straight onto your engine (all the sensors have the same plugs). Will save masses of re-wiring

Besides, if you fancied a many evenings, 60+ wire solder-athon by getting an S14 ECU plug, you might as well butcher an S13 harness as its actually the same plug, but more readily available

. In fact, your SR20DE plug, is that not the same as your PFC, too?

BenTaylor200 · 22-08-2006, 10:47

Good call, check if the ECU you've already got has the same plug

Rather than cut and solder it would probably be easier to just take the pins out of the plug and swap the wires over... But John likes doing things the hard way it seems...

thanks lads. i have sourced one here in ireland.
also i did look at my ecu plug and its the same size as the s14a harness. guess they changed them on the 1997 180sx with sr20de.
thanks for all the help. will go haome and whip out your guide john and get working.
thanks again.
will take as many pictures of the swap as i can as there isnt any guide for a de to det swap.
