I have a 1990 A-518 behind a '98 360 in my '83 RC.
A have the '90 MOPAR service manual for the transmission, and it shows a 3-pin connector for the O/D solenoid, and from what I can tell from the pictures, has fairly hefty wires that
power the solenoid. With gas prices into the stratosphere, I though it might be nice to use the O/D, but the only connector I can see (just above the shift lever) is a dinky 2-pin
connector. I know it is a O/D tranny, because the under-hood label identified it as such, and I had to use the shorter driveline because the tranny is a good foot or so longer than the one it replaced. I can't seem to find any information, and the local tranny shops aren't too free with info. Any help would be appreciated.

You are having problems wiring it up? The o/d switch is just an on/off switch. All you really need is a toggle switch for that and leave it one way or the other, depending on if you want it on or off. I think the other connector you saw (the 3 pin one) was the neutral safty/backup lamp switch.

IIRC, one wire is for the NSS, one for torque converter lockup, and one to activate OD. I will have to dig around to find which wire is which...maybe Chump will beat me to it

The Neutral safety switch is below, and towards the bottom of the tranny. The switch pictured in the manual looks a lot like the safety switch, but it clearly shows them both. The one on the tranny doesn't look like either of them. I can use the PCM
to control the O/D, but I have tried to apply power and ground to both of the leads on the road when a buddy was driving and nothing happens.
Thanks,

No lock up converter on a 90 A-518. The 90 fsm shows 3 wires going to the OD lock-out solenoid, but on my RC, I only see 2 also
