Hi,
I'm going to install a fuel pump power supply interrupt as part of an immobiliser; I'm probably going to site the interrupt point underneath the rear seat; can anyone tell me which colour wires run to the fuel pump?
KC Ron Carter - are you the guy that can post all those fab electrical diagrams?
Many thanks in advance.

Here's another link that works. But earliest model covered seems to be 1987.

When you say you want to install an 'immobilizer' do you mean what we N. Americans would call a 'kill switch' ; that is , an anti theft set up that requires the driver to activate some combination of in cabin switches (say the hazard lights & the a/c button) to override ?
If I was going to do that I would just put the interrupt on the crankshaft position sensor plug. It's right there at the back top of the motor and much easier to get at than the fuel pump wiring. Or maybe the main or fuel pump relays for the same reason. Disabling the main relay would also have the advantage that it would prevent the car from even being cranked and save yr battery from being killed dead by repeated efforts by the thief to start the car.[/url]
