Ok so heres what i workin with. i gotta 92 civic DX 4-door 5-speed and im going with the CRVTEC swap. So far the things i've bought to go towards this swap is a USDM B20b and a 95 GSR gauge cluster and im starting to shop around for everything else i need (tranny/ecu/axles/mounts/head/linkage/etc.) To keep ODB problems out of the way i've decided to use a 94-95 ODB-1 GSR head with ODB-1 p72 GSR ECU and complete GSR wiring harness. So i guess my question is, what wiring problems am i gonna run into with using the GSR harness in my 92 civic?

 

No wiring problems at all. You're in luck since you have a 92 Civic. ALL 92 Civic's regardless of the trim model are all prewired for VTEC on the cabin harness. Using the GSR engine harness will keep your wiring down to a minimum.
