Got some more mystery connectors for all you connector buffs out there (these all come out of the left side engine harness):

#2 (I think I figured out that the one with the green and the black wire is for the AC compressor)

I figured out that this goes here but still a mystery as to what this thing is:

from what i can see of your motor it looks aftermarket (and nice) so im guessing if you dont know what they are for you wont have the hookups on the motor

I just need to hook up a few things that are left over from the rochester to edlebrock carb switch, I know one of the wires coming out of the firewall is a choke heater and I'm wondering about hooking up the distributor too.

Pic 1 is the male end of the connector for electric power to the A/C blower motor - it is a separation in the line that goes to the resistor grid. The female connector should be in that area somewhere.

Pic 2 - left connector is for the A/C compressor clutch and the right connector could be for the idle stop solenoid or temperature gauge.

Pic 3 is your choke heater and another shot of your A/C blower motor line.

Pic 4 is your ESC module - since you're eliminating your computer you won't need it - this is the module the knock sensor connects to.

Pic 5 is hard to tell. I don't have this on my car, at least in the angle your shot shows. Can you show another angle? I almost wanted to say that it's for the blower motor resistor grid but I am not sure.

Thanks Silicon! Pic 5 is the backside of pic 4. I thought maybe the two things were related, ECM stuff I don't need anymore. I'll do some more digging in the electrical supplement and see if I get lucky. There's a nice diagram about c200 (or was it c100?) in the supplement that tells you all the wires coming out of that end of the firewall. It's overwhelming when you first look at it but then you begin to appreciate the way GM organized everything.
