RB20det wiring for S13

[Project_S13_180]

My friend installed his RB20 into his '90 240sx and all that is left is the wiring harness, how would he go about doing this? splice the KA harness with the RB? does anybody have any diagrams or something? or detailed directions, thanks

Search mah brutha, search. Its all here

Ill offer up a tip though, use the KA lower harness, it makes things a ton easier. The lower harness is the one connected to the chassis on the passneger side, controls the alternator, starter, battery termials, fuse box, and the transmission plugs. Swap out your KA speed sensor and Reverse sensor, that will make your speedo and reverse lights work no problem and save you some time.
