Clarify the renix stuff

[Cummins93]

Here is my current understanding of the early controller types.

 

Pre 87 had a single ecu connector? 

 

The 4.0 XJ and MJ had the 32 and 24 way female harness connectors for the renix ecu from 1987 to 1990? I can source the harness connectors but the ecu 56 way is rather difficult to find. Does anyone have a bad renix ecu and/or harness?

I had good luck getting a complete harness from a junkyard on the internet, 120$ shipped, installed and the truck runs/works normally. Looked like ECUs were expensive though, hopefully someone has one. 

 

i used car-part.com to find the harness

What are you looking for?  ECU and/or wiring harness?

 

I have a couple ECU: 87 ECU auto and 89/90 ECU auto.  (I have manual ECU, but not for sale.)

[Cummins93]

I would like to reproduce the connectors and make a pnp harness for the speeduino. I currently have them for the JTEC.

87 to 90 are are the same. I MIGHT have one.

 

 

[Cummins93]

What do you have? It can be in terrible condition as long as the connectors are intact. I have some test pieces coming by the end of the day. If I can confirm they line up then I may have a working solution.

I'll go look today.

I have ECUs but no plugs for them. A close-up pic of the ECU?

[Cummins93]

Can you post pics of the ecu plugs? Emphasis on the key ways and rough dimensions if you can. A simple dial caliper will be accurate enough.

[Cummins93]

Thanks. Yea those keyways look much different than what I have on the diagram.
