First thing I did was write up a wiring schematic. The RENIX system was much
different than the OBD-I based YJ. I had to get my hands on a factory wiring
diagram for an '87 Cherokee and a '93 Wrangler.
I placed the components approximately where I thought they should go and measured out the distances. I picked up a roll of 18 gauge wiring and spliced everything together using solder and heat shrink tubing.
