Micro tech X4 ingnition box quick wiring question.

[TheStitt]

Hi all

Started to wire my Microtech into the wagon, First time I've ever wired an ECU. Now I picked up the current 7M with the loom attached so it hasn't been to difficult.

However I have run into one problem. One wire I can't find an the micro tech diagrams.

I using these to diagrams

The wire I can't find a destination for. Runs straight from the coil packs plug. Its yellow and old mate had it going to a relay.

Is this ignition to the coils??

Any help would be great.

Thanks

The Yellow wire on the 6 pin plug is a coil negative wire.

I'd say your spot on, wire is actually orange.

I plugged it into the coil pack the the coil pack has three wires, 1 from each pack into the male of this plug. So I will earth my mystery connector
thanks

Or are the coil packs like the Injectors, they get a straight power feed and the earth through the ECU??

I had a second thought and thought this may have been a reason the last guy had the wire off a relay

from memory the microtechs are negative switching (switch by earthing). its been a while since ive looked at one/wired one up.

Coils usually get a +12V Ignition feed on their + terminal and the coil - terminal is switched through the igniter. (or ecu if it has internal igniters).

Running a LT10 not to sure Rudi.

I'll see if I can get some 7MGTE diagrams as the coils still have the factory wiring

Just spoke to a good mate who knows Micro tech,

Wire is 12v ing, ECU switches earths

thanks all
