hi can anyone help i have an onboard comp i want to fit to my 1990 xr3i efi can this be done if there is no plugs coming from my loom and if so does anyone know how cheers wullie

 

Hello mate

you need the loom for it, and the fuel computer looms for an EFI are like ROCKING HORSE SHIT to find!

I found one only a couple of months ago, first one ive ever seen.

A normal loom WILL NOT work, u have to have the EFI one.

 

Or at least to find out how to connect it to the ecu. A loom can always be made.

 

fuel coms are pretty easy to wire in mate, EFI even easier than MFI as 2 of the 3 sensor wires come of the ECU behind the centre console. The power plug should be hidden behind your clocks (yellow 3 pin), so the hardest wire to run is to the plug under the rear seat cushion, EFI FUEL COM wiring loom is the same as MFI its just one pin connection thats different!! The best way to do it is to get the fuel com multiplug off any injected escort and two feet of the cables behind it (ask anyone breaking an RST on ebay) so you can join it onto your new wires. so all in all you need to run 3 new wires. EASY. assuming your car has the fuel tank sensor. (black multiplug under rear seat)
