Hi,

I'm trying to locate the live feed to my S3 fuel pump somewhere behind the dash in order to insert an inline fuse; according to the wiring diagram it appears to be unfused - aaargh!, fed by a plain white wire from the ignition switch and with a junction which also feeds various warning lights and the ignition circuit. I could put the fuse in the boot near the pump but it would seem more sensible to place it as far upstream in the wiring as possible.

The wiring looms are original (42 years old now but in reasonable condition from what I can see) so I'm loathe to go poking about too much, so if any fellow S3-ers can point me in the right direction I'd be grateful. (Marek, I think you probably know where I need to look based on your post here: viewtopic.php?t=8361)

Many thanks,

Pop round for a cup of tea if you like - I am near Guildford.

The dash is currently off of the car, so I can point you to it quite easily. It is the big white bullet connector at the far rhs corner under the dashboard.

You will need to remove the dash to get to it, but you can also fit a relay to bypass the ignition switch at the same time and thus double your good work all at once.

kind regards
Marek

Marek,

Many thanks - I've sent you an email.

Regards,

This helps me thanks as I have a short going down to the fuel pump, any idea what the cotton braided (white /black) wire is on the right hand side of fuse box, more to point where does it connect to

Dear Jon,

If you look at the wiring diagram, you'll see it is for the heated rear windscreen. You obviously don't have one.

It also sounds as though you have may have melted the unfused white wire which runs to the fuel pump. Check its continuity and resistance.

kind regards
Marek

Cheers Marek, I do have a heated rear screen which never worked, thanks to you it does now RESULT. Checking the feed to the pump from the ignition and it has a break in it somewhere so I will run a new feed and fuse it.
