Neutral safety switch questions??

jasonn · Jul 14, 2004

My 70 won't start. Originaly an fmx car so the switch is under the shifter. Has had a c-4 in it for years and everything has worked great till last night. First, Why the 4 wires? How many should have power and and when?? Second has anyone tried to bypass and if so how?? I tried to jumper all the different wires and could only get the thing to turn over when you turned the key to the "on" position, not the start. Any help would be greatly appreciated. Thanks!!

I dont know about your 70 model, but my 67 has four wires. Two are for the switch and the other two are for the backup lights. You can tie the right two together and make it work. But it will work in any gear. So you have to becarefull. When they start in gear things go wrong quick. Figure out the backup lights wires. The other two will be the neutral safety wires. Mine come out of the firewall where the wires to the coil and sender harness is. Also if I remember right one of those four wires has two piggy backed together. Thats the one to the lights. That plug has two male and two female ends. It goes male to female next to each other. If that makes sense. So it should look like this.

Tie the X and O together that sit side by side. It should work then. Now remember this is based on my 67. Your 70 might be different?

2 wires are for backup l;ights, and 2 for neutral switch, I'll get you the colors in a sec

EDIT; black/red and Orange/yellow is backup lights

red/blue and red/blue is neutral safety switch

orange/ yellow should be hot and one of the red/blue should be hot on crank only, the other will be hot if the switch is good.

Neutral safety switch questions??
