I picked up a half finished RB20 project a few weeks ago. It's an A31 with an R32 motor and a C33 KS-ROM ecu...(?) It has extra electrical connectors. I can't find a wiring diagram for an A31. The car runs and idles but is difficult to start. Any ideas?

8pin with only 2 wires: sky-blue & green/orange.

2pin: brown & black

Extra cable.. probably doesn't go to this car.

Looks like an injector resistor, but the connector is hacked off and shorted together.

Nothing connected to the air conditioning.

right, i think your first photo is showing the old anti lock braking system plugs off the half cut loom. cant quite see if one of those plug has fibreglass insulation on it, if it does it will be the o2 sensor in the out let manifold. the shot with just the plugs one of them looks like the loom which used to go to the old auto trans and the othe one looks like the plug which brings power over to the computer and the power from the dropping resiter for the injectors throuh the head light loom. if it is running though it shoud be sweet and not need the othe wires. not 100% though, good luck! definately a injector resister in there, not sure of the rb20 but the 26 needs a injector resister with 7 wires coming out of it, so not needed.

      GOT SUM's RB34

      By klutched · Posted

      Got some decent progress after work yesterday and also today. Got the ECU all wired and passenger side interior all back together. Kept the wiring up nice and high to avoid people standing on it. Got the surge tank relays rewired and tidied up the pump wiring and cut a hole to bring the cables through.  I found a spare USB cable I had lying around so I decided to cut it up and see if I could use it for my CAN 1 bus. Turned out one of the pins I needed was to the shield of the cable so i cut it up and desoldered it and resoldered to the correct pins.  Had the issue with the powersteering hose hitting the A/C compressor and fan shroud. I pulled the bracket off and modified it to remove the front mounting point which now clears it all. Will keep an eye on it to see if theres any signs of fouling once it's up and running.

      So today I went well outside my comfort zone (again) to replace my valve cover gasket.  I have had a big leak over the exhaust leading to a lot of smoke and smell every time I drove it. The leak was in the rear driver's corner.  The job wasn't hard as such, just a bit finicky and time consuming.  The old gasket was rock hard and broken right where the leak was.  The leaky corner had so much sitting oil in it.  The good news to my amateur eyes was no buildup or sludge under the cover. It all looked fairly nice in there.   I haven't started it yet. I ran out of light and body when putting the coils and injector loom back in. Probs only 30min left for the morning.  I was so nervous putting the cover back on, I must have lifted it 5 times to make sure the gasket was still seated properly. God it's going to be nice to be leak free and not make other traffic light queuers think my car is about to explode.

      Gave the Mazda it's first wash, it will need some clay, a light compound, and polish polish to remove a few swirl marks, but that will be a job for when I have a full day to get my DA polisher action on

      Just did this job on my 32 with the boost doc kit. was quite simple to fit, hardest part was getting the rubber bungs back on the firewall. does anyone know how the heater will work now without the flap in the bend? Will I just have a heater on 24/7 now?
