Thanks for that. Yes, the car runs, but not well. I need to send the carb out to TTA Performance for rebuild. It was rebuilt before I got it and it's not done right. It fails to idle correctly and wants to die in closed loop, and once the computer takes over it starts running better but still not right.
I haven't had the turbo kick in yet as it's not running well enough ahead of the turbo to spool it up. I'm learning about the turbo.
I did the usual to it - tune up and plugs. I have the cap, rotor and wires and just need to find time to put them on. Found the cat was clogged so I cut that out and I'm just running open at the downpipe at the moment while I get the rear exhaust hung right.
I was getting a CEL in open loop intermittently and that's gone away. I either disconnected something when pulling the radio, the bulb died, or the computer is happier at the moment. Pulling the plugs for the MAP and Baro sensors don't throw a CEL so I'm thinking the bulb is burnt out.
It's got small issues all over. On top of all of it I am pretty sure it's burning old gas mixed with new gas and none of it is any more than 87 octane.
The turbo light switch on an 81 is near the console, not in the dash. Turbo lights work. At least low brightness in normal (no boost) mode works. I haven't seen the others light up and have to address that at some point, but I need to get the carb rebuilt, ensure the turbo is working, then I'll worry about those if they don't light.
The long-winded answer is that I'm pretty sure everything is working in the dash at the moment except the fuel gauge and I believe that's the sender. I think this mystery bundle of wires is from an unused connector and whoever "installed" the aftermarket radio cut it and didn't use anything from it.
