I recently bought a 1981 hilux single cab with a 1994 22re/w56 swap. the 1994 harness has been fitted well and isnt chopped up. I am wondering if anyone has any info on retrofitting a 1994 22re harness to function with the 1st gen cluster. i am currently running a filed 1994 speedo cluster with no tach and i dont mind but i still have the original cluster and could mount it properly instead. any info on wiring diagrams or specifics to simplifying a 94 harness to fit would be much appreciated
