'85 245 Non-Turbo 120k miles

This is my old 245 now owned by a friend and I gave him (essentially) a lifetime warranty and am trying to get him back on the road.

Symptom: No Spark

Voltage to coil. Did the diagnostics in the Bentley and it came up a bad pickup/trigger unit. Car has the Chrysler ignition module but NOT the distributor shown as normal for this vehicle. (I posted the information in an earlier post I can't locate now), but I got the Bosch Part # off the old Hall Effect Sensor in the distributor and located one on ebay eventually (NOT easy to come by).

It came w/out the base (that was shown in the illustration of what I bought) so had to mount it on the stock base (it was crimped on originally, NOT easy!)

Went to plug the harness into the new pick-up and darned if the harness plug is DIFFERENT from the new one (slightly, but ont plug in).

The size of the harness plug is SLIGHTLY bigger then the hole in the Trigger Unit Socket, and the flat-blade spacing in not linear in the Trigger, where as in the harness the contacts are equally spaced apart (see illustrations below).

Question is if I put new connectors on the Trigger Unit and the Vehicle Harness (mating ones I can buy and splice in), is this the right way to do it?

The Bentley (Manual L293 for 1983-1993 Volvo 240) shows Pg 390-26 that the Module has 6 wires (ours has 9 wires) but shows the harness connector numbered 1,2,3 connected to the Distributor #s (-), (0), and (+) respectively, but the harness wire colors in the Bently do NOT match the car's wire colors.

The Bentley Ignition Sys Chapter (Pg 280-2) shows the Chrysler Ignition picture (No color Codes or #s). The Distributor Harness Plug and Distributor Socket match the Bosch pictures shown on Bentley Pg 280-9 Fig 15 and 16 despite having a Chrysler Module. And the distributor itself IS a Bosch, but the Part # does not match anything I found for any '83, '84, '85, or '86 240 or later 740 Distributor. It showed our distributor was for a VW in fact, but it obviously fit, plugged in, and worked for 35 years.

QUESTION: Would you just hook Harness Pin 1 to Dist (-), Harness 2 to Dist (0), and Harness Pin (+) as shown in the Bentley? The Bentley and Car Harness colors are different. (I figure the chances of finding a harness plug that will match the distributor pick-up socket would be close to zero, but I can find an after-market matching set to graft in.).

Car Harness #1 is Black (Bentley shows SB or Black)
Car Harness #2 is Yellow (Bentley shows BL-Y Blue/Yel)
Car Harness #3 is Green (Bentley shows R-R Yel/Red)

Trigger Wire Colors can be seen inside distributor where they connect to to the socket on the trigger unit)
Trigger Wire (-) Black
Trigger Wire (0) Green
Trigger Wire 9+) Red

I ASSUME (dangerous?) that the Trigger wires are hooked to the trigger socket terminals as were the old ones (unfortunately that was thrown out before realizing the harness plug was slightly "off" sized from the trigger unit socket so cannot compare now).

My concern is we hook up the harness-to-trigger incorrectly we could damage the trigger unit? I would feel more comfortable if a Bentley Wiring Diagram matched the vehicle better (I looked at all years and none are like ours).

The car is almost 30mi from my house, so unfortunately I am trying to limit my 60mi round-trips to new owner's place.

I am going to attempt to post photos of the components-

Thanks in advance if anyone has a clue.
