Still on the wiring in my EcoTec engined Triumph TR7.

I've connected the Plug 3 (Grey) Orange wire to 12V Battery (Permanent live),
and the Plug 3 (Grey) Pink wire to Ignition Switched 12V.

Are there any more Ignition Switched 12v supplies for the PCM?

The switch is always mounted on the sifter in the cabin on those.

:?
I'm looking to see if I've got all the 12v Ignition Switched PCM supplies hooked up.

Hi Stag76,
Is this still just a check list, or have you been attempting to start

Still a check list.

Hope to try a start in the next week or so.

Got the engine running OK.
The only issue I have so far is that the cooling fan starts approx 5-10 seconds after the engine starts
and runs continuously, even though everything is cold.
I've tried disconnecting the coolant temp sensor in case it was permanently grounding, but it made no change.
I'm using the Blue/White wire from engine loom connecting plug 1 to ground the relay.
Does this sound like the correct wiring?
I can always fit another switch to drive it.

Any codes?
Are you using memcal or NVRAM.
Does the 'system check' 12 CEL flash work.
Good effort to get it up and running :driving:

It’s been a long time since I done a conversion with one of these pcm, but from memory you have to disable the low speed fan without a bcm. I think if the pcm picks up no bcm it will automatically turn on the high speed fan cause it thinks the bcm has a fault therefore the low speed might not work.
This is trying to shake the grey matter though.
