The manual conversion with an auto ecu probably will give issues but I reckon there is a simple fix. I'd simply add a microswitch to the throttle linkage so any time you come off idle, it closes the circuit for the gear recognition. That way its always "in Drive" when you rev it.
Regardless, that'll be a really cool build. Cant wait to see it come together.

Welp....help....[emoji1787] I have a thread in the 202 section on BW(🫤 no pics, format is so crap over there) so i just copied this because it's a lot to write out.
Whoaaaaa baby!! [emoji51]. I bought the car. With the fuel leak and it sitting for years I unplugged the pump and just cranked it to hear all the rods were in it. No bad sounds. Trusted the seller that it ran great when parked. Maybe not a great move. We'll see. Where to start..
Positives. Not really rusty for the most part. Interior is really nice although it's all coming out soon. Engine seems smooth (when all cyl are firing) and quiet (like valvetrain wise, cause the exhaust is wide open). It's moves and stops.
Neg.
Major electrical gremlins. I may have a couple clues.
1. hooked up a battery once I got home after I opened the fuel rail put a hose on it and fixed the fuel leak at the pump. Ran the pump off a jump pack and only a small amount of awful varnish came out. Added 4 gallons. Tried to start it. Missing horribly. Realized the pump was just running no matter what. Found a jumper wire in the fuel pump relay plug...oh boy. Messed with a bunch of stuff, relay is good, fuse in it is good. It's definitely mixed with some stinky crap that didn't pump out though. Probably not helping the missing issue. Plugs[emoji1745]
2.Found it's not charging either. Great. Checked an cleaned all fuses with a wire brush to be sure. I've gotten it to run clear for moments then it reverts to 2-4 cyl at this point .Tried testing injector output and got confused by constant power at the plug(then did research and found that's correct).
3. Notice most of the dash lights are on with KOEOff but will blink kinda sporadic. I thought it was code at first but it's not. Only thing that stops it is pulling the cluster fuse. No other circuits or relays seem to affect it. At this point it's running better but still not right all the time. I'm using a big charger on 10 or 40 amp to keep it running. In the two pics one is a single frame of the dumping of the lights. This is engine off just sitting there. Nothing shaking the car, no relays clicking or anything. It will just flash off. While running it will flash on. It kinda seems to do it worse when the charger is off but it's hard to say.
4. I have decided I need to get the alt working and try to figure out the fuel pump relay issue but I noticed there was a small whining sound coming from down near the throttle body I think wouldn't shut off with battery hooked up until I disconnected the engine harness plug from the ECU(I'm pretty sure). Then it didn't repeat after I cleaned up and moved the car off the dolly and jack to its parking spot.
Sooooo. Reading I've done so far seems to suggest voltage regulator could be part of the dash issue and the flash while running(which cuts the tach also) seems to coincide with a stumble or serious cylinder dropping. Also the OVP relay has been mentioned which I'm not certain which one it is in this car. There's a bunch of relays with fuses strewn about under hood , in the back half of the fuse box(need to unscrew the top to get at them) and over by the ECU bank. There was times it would refuse to start and just pop on one cyl but was idling nice and revving ok a lot of the time. I drove it across my lot and parked and it seemed very peppy.
The wiring LOOKS ok not cracked at all, but I'm not sure if it's a replaced engine harnes or not. The MAF plug shows what looks like a 6/97 to me but the tag sure appears to be 26.8.93 (8 26 93 IN AMERICAN DATE ORDER) and the 202 540 4032 number comes up delphi improved design.. I'm going to concentrate on getting the changing system going then move to rural pump relay. The other main issue is no exhaust after the two pipes come together for an inch or two and no O2 sensors. Neither helping for stumbles and stuff. I'm working on figuring out at least a temporary solution for that too. The front O2 plug is damaged so I'll need to address that as well.
[emoji1745]🫠 any insights throw my way will be appreciated.
