Weird Wiring loom setup.??

[murphykidd]

Hi lads, just picked up a 325i today for the e36 and with the loom that's on it there is 2 plugs that look like they fit the ecu.? Is this normal for a 94 325 engine .? I'm abit confused as to why there would be 2 of these plugs on the loom.? Any one here come across something like this.?

This is what i have on the loom? Any idea by anyone as why it's setup like this.? Don't want to plug any1 in and try start it incase I do an absolute f**k up of a job when it try's to turn over.

I think that's an automatic loom mate, the other plug would be for the gearbox ECU which goes in the same compartment as the regular ECU

Is it no good to me so for running a manual?
