I have a 1972 Grabber with a factory 302 and floor shift C4. I am converting the C4 to an AOD. The neutral safety switch on the AOD has 4 wires going to it but the neutral safety switch on the C4 has 6 wires going to it. I was wondering if anyone had a wire diagram of a 6 wire set-up for a C4 so I know what wires go where. What do I do with the extra 2 wires?
Hi Nick, you could trace the wires in the C-4 plug to match the ones in the AOD plug....you do have the AOD plug? my C-4 NSS only had 4 wires. hope this helps.
I have the plug for the AOD transmission and know where the wires are supposed to hook up to. My neutral safety switch has six wires, that is what is confusing.
The neutral safety is generally red/blue(in and out), backup power is probably white/pink and maybe black/pink for exit to lamps... Other two I dunno, doubt they are even necessary... I'd leave 'em disconnected and if something doesn't work connect them together... I have new one of those 6 wire switches out in garage, later I'll look at the colors..
My switch has seven wires!!! Of course it's for floor shift and includes socket for quadrant illumination... The additional two wires are lt green and purple with white hashes, apparently those colors are associated with brake warning light circuit... Except for park, on my switch those have continual continuity...
My switch has seven wires also if you want to count the brown one for the floor shift illumination. I am going to assume the two red with blue stripe wires connect to pin 3 and 4 (neutral safety), the white with pink stripe wire and the black with pink stripe wire connect to pin 1 and 2 (reverse lights). The green wire and the white with purple hashes wire will be left disconnected. I do not have a brake warning light connected anymore.
Mine is the SAME thing!!!! one connector has 4 wires and the other has 2 wires. I need to change my switch and I can't find out which switch to use! Did you ever find out anything?
