your post doesnt make much sense. but im assuming your putting a 20det into a car that was originally 20de ??

if thats the case there isnt any cutting of wires involved. you just feed through the det engine harness to the cars loom and plug it all in.....

I can't tell you what wire to cut and connect, but here are the loom pinouts for A31 I found this on a jap site www.a31cefiro.com

It includes loom pinouts for RB20E, RB20DET and RB25DE in early, mid and late models.

The ECU pinout is the same as the R32 RB20, but this includes the pinout for the dash loom and consult connectors, so would be very useful for anyone doing an engine conversion in their A31/C33

Google translator does an okay job of translating the wiring descriptions but a couple of them come out funny.

early model

mid model (consult)

late model (includes rb25de)

Just spent the last couple hours checking out the rest of the site, there is heaps of information and specs there.

Tailshaft lengths, brake master cylinder bore sizes (and booster diameters), radiator core dimensions for different spec levels on R32/A31/C33/S13.
