Loom wiring diagram

[Vixpy1]

Has anybody got a wiring diagram of the engine loom? Got an ECU pinout but it would really help having the whole loom plan

Just the engine management side, or the whole of the electrical system? For the latter, Steve Heath's books include wiring diagrams from the factory which are probably the best you're going to find.

Just the engine management side, ie, the main engine control loom.

Almost everything goes straight from the ECU connector to the corresponding plug on the engine. The only exceptions that spring to mind are 12V permanent and ignition feed, vehicle speed input, and output to the pump (via the pump / lambda heater relay and inertial cut-off switch).

Yes, I've been looking at the loom I have here, its always good to have a wiring diagram when your about to butcher something

i think I need to buy the bible.

You could try the Phil Ringwood site.
Scroll down to TVR EFI hot wire diagram.
The drawing shows the TVR circuit diagram with the mods to the Megasquirt ECU but it gives you the
general idea.

Ah excellent! Thank you

Is the best place to buy the Bible off Steve Heath himself?
