Pin 11 and 12 grounds.
Pin 29 to brake switch

Pin 51 Switched ground wire to Pin 86 on ASD and fuel pump relay
Pin 57 pin on 87 on ASD relay
I also had a 1994 Dakota Service manual and a good understanding of
electronics. Hope this helps I think you may still find this in the tech archives also


Awesome. THANKS!!! up

Dont let the amount of wires scare you. I just hung the ECM end of the wires from the ceiling and saved all the sensor and feed wire wraps from the factory. You just need to feed the ECM power for memory and Ignition.
The 2 relays feed power to the fuel pump,And the ASD relay keeps things running if there is no problems. OBD1 is quite simple information in information out..

IIRC the 80's injected Chargers and maybe others used a speed sensor that connected to the trans and then the speedo cable connected to the sensor so you could have both. I don't know if they used the same counter though. But I think there are only 4 poles in the sensor. If you keep the speed sensor and brake light switch signals you won't have to use switches for the O/D and lockup.

I'm going to swap a complete 93 Ram Charger dash, engine, HVAC, fuel tank and wiring harnesses into my 74 crew cab. I plan to use everything from the RC including the steering column so mine should be easy. What I would like to do though is an OBD II swap for the engine management so I can modify the engine with an intake, cam and heads. The hot wire harness looks like an easy way to go but at $1000 it's pretty steep. Especially when you consider you still have to get a PCM and tune it as well. So it may remain stock for awhile.

STANDARD MOTOR PRODUCTS SC108 is the sensor for older transmissions that lets you keep the cable and still have an electronic signal for the computer. But you'd need the pinion adapters to put into the 95 setup.

You know I can't remember how the 95 Dakota tail housing with the sensor looks. Does the 95 still have a governor?

Looks like a maybe, might have to slide under the truck and just look.

Why does the ECU need an electronic speedo signal?? I know the 95 dakota speedo needs the transducer because it has an electronic speedo, but what does the ECU need the signal for?
Sorry but I'm old school, I have limited EFI experience!! smile

It needs to know the vehicle speed not just for O/D and cruise but also know the vehicle is not just sitting still. Early efi cars would stall on decell without a vss signal.

Is there a way to run speedo signal while at the same time running a mechanical speedo cable?
