Hi guys, am almost finished installing an Elite 1500 on my Honda K20 type R powered Lotus 23, but i've hit the wall with the alternator connections,
i've never come across a 4 wire alt before so Im stumped, i can identify and connect the blk/yellow ign, and the white/blue warning light,
but the Alt FR signal [B13] on OEM ECU and the white /green control signal [B18] on the OEM ECU have me completely bamboozled.
can anybody shed some light for me as to wiring them into the ECU
much appreciated John

i take it its a 4 wire regulator connection?
if you have the terminals labeled on the alternator then this chart may help.

worth noting that the monitor terminal doesnt need connecting when running a stand alone as its just for the factory ecu to know what load is on the alternator
