need help please. i picked up a 98 gsr that someone had put a 99 ls motor in, dont ask why. i got my hands on a 96 gsr eng and put it in the 98 gsr. there is a 3 wire plug on the p/s eng harness that has nowhere to go on the 98 chassis harness. i got the haynes manual and there are 2 different wiring schematics for 97 down and 98 up. also has an active code 1259 - vtec malf. i believe it is a wiring and electrical problem but need some help to figure out.
