alternator connector issue's

[Matt tynan]

Hello lads, ive been following this forum for a good while now and decided to sing up, im in a bit of bother with my alternator on my b18c, basically i have a b18c from a 98 spec dc2 which as far as i know is obd2a, correct ne if im wrong, i also have an engine loom from a ek4 vti pre facelift, which should also be obd2a, but the connector for the alternator is only a 3 pin, whereas the the alternator itself is 4 pin, does anyone know an alternator that will bolt straight up to my b18 and os also 3 pin, thanks in advance

All UK cars have a the 3 pin connector (obd2 cars) obd1 is a round plug so won't fit. It looks like you have a US alternator.

Best bet is a mb6 alternator or go on Facebook I'm sure someone will sell you a b series alternator with right plug cheap.

I actually figured it out mate, turns out even though both looms are obd2a the ek4 vti alternator is only a 3 pin, whereas the dc2 r has a 4 pin like the ek9, all thats needed is a vti alternator, my b18c is type r, definitely not US, thanks anyway for the reply mate appreciate it

Edit: still haven't solved the problem, i could get a vti alternator but would have error code 20 as i have a p73 jdm ecu which supports ELD (electrical load detection)

Search Google "b series alternator plug" you'll find the square 4 pin plug is American. I have both a facelift ek9 loom on my ek and a pre facelift sitting in the shed, both have 3 pin plug.

I have a jdm dc2 b18c, and the teg loom also is 4 pin, dont know much about mb6 to be honest, different specs for different countries i suppose really

That's a 96 spec JDM DC2 Alternator with square plug (Denso), You need one from a B18C6 UKDM DC2 (Mitsubishi) to be 100%, Others will fit but this solved my problem recently.
