Well lads. I want to put a push button in to start the car but I still want to use the keys to turn on the ignition. Just want to bypass the barrel/Ignition switch really for turning over the engine. I've got 4 wires coming off the barrel. Blue/Black, Red, Yellow and Black. I've got a multimeter to hand and the manual for the car as well with the wiring diagrams if need be. Just need a little guidance here. Thanks
