Accellerator enrichment valve
Also, just to confirm my research - can anyone tell me the colours that each of the 2 pin plugs on the engine loom should go to.
Appreciate any advice.

The accelleration enrichment valve is attached to the metering head and the plug (black) is connected to it!

The throttle valve switch is on the throttle body. You can see the green electrical plug attached to it. You'll need the correct throttle body to attach it I expect :dontknow:
I'm not sure what benefit the system gives though?

As far as the throttle body switch, I have the switch on the throttle, but nothing on the loom (which is intact) so I guess I can't make use of this either. As you say, I can't make out what benefit it has either. Perhaps someone else could enlighten.

Throttle valve switch
The throttle valve switch is for cold enrichment when first accelerating. The thermo time switch should work in line with the throttle switch and cold start vacuum switch so when you first accelerate when cold the 5th injector puts some fuel in also to help with the cold manifold and give a nice power level. Only for 0.4 secs though. When the engine or thermo time switch is over 35 degrees the cold acceleration does not work as the thermo time switch goes to open circuit, stopping any 12v supply to the 5th injector.
Big bother with mine at present, doing my head in.
