Trying to start installation of a 'Unichip' by dastek which is a piggyback computer for cars that don't have a lot of aftermarket support-you know saturn didn't I'm sure. Question: do you know of any other cars that had very similar, albeit not exact, harness connections for their pcms? Reason being, Dastek has hundreds of diagrams for various makes that detail what wires to intercept (how to intercept-cut and splice, 't' into, etc.) but naturally, not for the saturn. Having one that is close, might might help them to help me, would be fantastic. Sounds like you delve into a lot of pcms and perhaps you've seen one close to that particular setup. I specifically mean number of connectors, their number of pins per connector, etc.





192.168.100.1 192.168.1.1

 

Moved from some irrelevant location to here.
Please get with the program.

THere probably is a match because I doubt Motorola would make a PCM for one vehicle line only, but who knows. Plus they changed PCM suppliers over the years, at least for the s cars.

I would grab the PCM part number off your Saturn and look outwards to see if you can find a match.

Never really thought of it because I've never messed with PCMs

 

This is extremely interesting. Back in the 80s I used Ford Duraspark 2 ignition boxes on anything that had a pickup in the distributor. That has now become GM HEI distributors for many different applications.
A generic PCM that only needs a crank sensor and cam sensor input, either speed density or mass air flow inputs. Either cable throttle plates or pedal by wire with easily sourced components. Like the put an LS in anything pcms and harnesses.
