looking at the tech section someone made a drawing and refers to pin 3 as the tacho/rpm signal
any help appreciated

or is it another one of the relays in there
theres also a small 5 pin cartier

yes mate thats it you can bypass it if need be too till you replace it, its the 6 pin relay:agree:

[R5MJH]

sorry yes think scoff mentioned it recently the grey wire on pin3 i think

[Corty]

thanks very much
im guessing one of those white wires is kind of grey ?

well here goes nothing it'll either work
or smoke will escape from it ...........
:confused:

[Corty]

just been playing with this relay (white 6pin) as the colour are crap - nothing like scoff has said mine are white purple .!!
then noticed when i manually activate the central locking this clicks
thus tells me this has to be the central locking relay
not the fuel pump relay ???????

anyone shed some light ?
or can u direct me to the correct wire on the AEI unit
the car has a toad alarm/immobiliser and a lazer immobiliser
im guessing the wires have been screwed with by the alarm fitter!!

[Corty]

This is a central locking Relay !
after searching for the same thing a few posts come back

so wheres the bloody fuel pump relay !!!

THANK YOU !! time to go rip the dash apart and hunt the little Bas:scared: out!

No worries :) Keep us informed! :)

IT wont be on the fuel pump relay.

Take it from the back of the clocks

If you've got a haynes manual have a look in the wiring diagram, it'll tell you the exact wire, I can't for the life of me remember the colour now

Both verify its pin A8 on the back of the cluster.

Oh yes it is Dave :)

Fuel pump relay as follows:

Thick red = Battery +ve
Thick white = Fuel pump +ve
Thin black = ground
Thin yellow = ignition +ve
Thin brown/grey = tacho

The relay watches the tacho signal to decide when to switch the pump on and off.

When I fit ECU's for EFI conversions I wire everything bar the ground to the old fuel pump relay.

...so wheres the bloody fuel pump relay ???
Yeah, I've searched high and low on here for its position. Here's the base of the
white one, compared to the base of the green one I have, which matches the
picture of those for sale in the RTOC shop.

Any ideas guys?

Fuel pump relay attaches on a small bracket at the top right hand side of the fuse board. It's also a large rectangular cartier

Or just left dangling/stuffed behind the fuse box like most seem to be!
