Connect to the brake controller and route the black and blue wires. Find the blue wire that comes off of your electronic brake controller. Attach the blue wire that came with your 7-wire plug to this blue wire. Locate the rubber grommet that surrounds the interior wiring harness where it feeds through the firewall.

mk 2 escort ,nice car in its time i must have welded no end of sills on these cars for the old MOT ,did have a haynes book laying around but the mice ate it ,right these old cars always had problems with the bulb holders corroding ,so check these out first ,the wiring is simple enough though a feed runs to the 3 pin flasher unit and from their the feed goes to the stalk switch which then sends it down either side of the car so put the indcator on then check for a feed to the light and if you have a feed then the problem is the bulb holder ,so have a play and see what happens ,i used to build these engines on the assembly line in ford dagenham many moons ago .

I don't think that they offer wiring diagrams. I would check out autozone.com. Register to use the full version of their web site and check out the "vehicle repair guides" or "specifications". I think that the wiring diagrams are located in specifications, under chassis electrical.

instead of fill it gas i axcedently fill it with diesel please let me know what to do and by the way i did not use it cause it start shirffing when oi press on the gas
