I have the diagrams, but they dont seem to make any sense. The JWT page shows the RED/GRN wire as the signal wire and the White being the 12v wire. Correct me if i am wrong, but doesnt red usually imply power?? I would like advice from someone who has done this please....here is a pic rb20 left, z32 right. [IMG][/IMG]

I would think the Two sheilded wires, one white, one black connect. then the two remaining black wires get spliced, then i would pair up the red/grn with the last wire being blk/wht. Does that sound about right??

I used this when I did mine and never had a problem.

Z32 connections are marked A to F but only four connections are used when fitting to the rb20det.This wiring diagram is based on fitting a z32 afm to a r32 gts-t.A: Blank offB: connect to Black wireC: connect to black/silverD: connect to whiteE: connect to black with white traceF: Blank off

e = +12Vb = OUTPUT VOLTAGEc = - ground (ecu)d = - Body ground
