e30 m20b25 manual conversion wiring

Recommended Posts

Nearly finished my conversion but my car had the sport switch auto and the wiring is different to all the diy guides I can find. Some show cutting out the auto plug and joining 5 wires, others show alterations under the dash. Anyone know this?

I did this late last year. there is a plug in the glove box you disconnect or connect. I can remember which. Have a look on e30zone there are plenty of threads about it.

wiring for the inhibitor is the same.

do whatever you want with the sport switch, leave it there / unplug it whatever.

from memory, there are 5 wires there, you leave two of them crimped off to themselves, and the other three you join all together is that right? havent done a manual conversion for like 5 years now.

The E30zone thread was correct. Up behind and above the glovebox there is a thick loom strand with two single wires bound to it. each is a blk/yel to blk with an inline plug. Undo these, connect the blk/yel's to each other using the existing plugs and its sorted. Have some pics i may try to upload. The reverse lights seem pretty simple.

Now woundering about deleting the redundant loom and trans ECU? before i re-assemble the dash.

Perhaps that ECU behind the glovebox is not for the Trans? Ill leave it there.

THanks Chris00 for the right info.
