M@tt 77 Posted October 5, 2006 I've been helping Chris (309Pug) with stripping the un necessary wiring out of his track car ready for fitting his DTA management. I am correct in thinking the Tachymetric relay can be binned can't it? The wiring diagram for the DTA management indicates a wire from pin10 (iirc) of the ecu connector to a fuel pump relay which i assume would just be a standard 4 pin relay. and i assume the wire from the ecu will pull to ground and open the secondary circuiit to the fuel pump which will allow it to work. One of the 3 relays that are usually attached to the bulkhead (horn, fogs etc) would be suitable to use wouldn't it? Cheers Matt Share this post Link to post Share on other sites

Sandy 191 Posted October 5, 2006 I run the fuel pump throguh one relay, with the command earthed through the ECU as you say, the ECU will turn the pump off when the engine stops, good for safety. I put a hidden switch in the pump supply to so I can turn the engine over with the pump off or immobilise it. I run the ECU/Injectors/coil of another relay switched by the ignition switch circuit, to keep the current low through the interior loom. Share this post Link to post Share on other sites
