V6 Electrical Plug Identification
Posted 26 June 2017 - 10:06 AM
I brought a V6 conversion that came out of an old friends car. My mate brought this from spoox several years ago. He then sold this conversion after a couple years and it was owned by another guy for awhile until the car was hit and written off. I by chance found the guy and brought the conversion package that he removed. I have reahelled it by redone most bits and redone the conversion to a better standard that Iam happy with. It's all done now but won't start. It was turning over ok but fuel pump won't prime.
I've reused the conversion loom I was given and plugged it all in bar one multiplug that is next to the ECU and two relays. I have nothing to plug this into and unsire if needs plugging into something but don't have anything so presume there was possibly another small lead it went into that I didn't receive.
I've found numbers on the wires but very faint and I can't identify the wires from the few diagrams I've found from search's. I'll try post a pic of plug and wires.
The codes are (I think) :
M1630 yellow green stripes

cruise control module from memory.

Guessing that leaves me with either:
relays (which I'll try bridge tonight to eliminate those)
Other wiring (altho was a running conversion before)
Or ECU (supposedly already unlocked

should be easy enough to figure out, do you have a permanent 12v at the relays, then look for the switched 12v, check for the inertia switch, bell out the wiring to the pump.

Had a look lastnight and think I've got no spark or fuel. I fear either my ECU has locked out or the wiring damaged somewhere.
Only one of the two relays has wite to both pin 5+8 so shorted that one and the pump still didn't prime. I've really no idea what they did to the wiring altho it worked in previous car it's not now. There's one other small grey plug next to the ECU and relays that's not plugged in. Looks like a sensor plug I guessed was for carbon canister thingy but I noticed one of the wires goes to pin 6 of one of the relays. Then it's joined and goes off somewhere else.. one of the wires is green 1223
Think I'm going send ECU off see if they can check it and decode (altho they said not sure if can do this ECU)
And failing that I might need a look making up

I have an unlocked and tested bosch MP7.0 ECU for sale. £50 including postage and packing. Or i can bring it to Pugfest this weekend.

You have checked the inertia switch if it still has one haven't you?
Mine was a relay problem, I had to jump two wires as one wasn't getting 12v, you hear both relays click and you know you are good to go.

Relay 1 should have 12 volts on pins 2,11,14,8,15
Relay 2 should have 12 volts on pins 14,8,11 and pin 7 should be earth.

Got an old multi meter out and I've got no power at the relay with more wires which I think is fuel relay. And the one with less wires only has power at pin 14 ?!?;
No idea what's going on

i do, you have no power, therefore you need to figure out why.
probably not connected the main power supply, or a broken wire.

Unless the grey small plug or that bigger black one was being used to supply power??

I have one of Ade's v6 looms (and a cruise control loom), although I've not actually fitted it yet it looks bloody brilliant! Very well made and the ECU is in the correct place.
