3.2 conversion blower question

[inaminit]

Yet another 3.2 conversion question! Wayne should do a book that answers all these questions in one place.
The car is a 76, the engine an 86. The 76 has a fresh air blower in the front trunk operated by the sliding lever control box. The 86 has a supplemental blower on the engine which I want to utilize. How would you wire in the engine blower? Also, I have seen a blower motor resistor offered for sale. Do I need one of these? Thanks in advance

I personaly found it best to backdate the heat using the parts from my 1973 onto the 1986 engine.

Thanks for your answer. Thinking about it some more-the rear blower fan cage is in the duct that carries air down to the exchangers and then forward to the fresh air blower. If it wasn't running whenever the front air control calls for air, then it would act as a drag on the air stream. So maybe it should run all the time?
I have had a 72, and currently have a 90 c2-the rear booster fan in it makes a wonderful difference in the amount of air delivered. So I am convinced that I want to retain the rear blower.

I see no problem in keeping the electric blower, especially if you are keeping the stock '86 exhaust. It serves the same purpose as the original ducting on the earlier cars, just substituting an electric fan instead of the engine fan. Here is the electrical for the '86. I don't know what the blower control function is, but you can put a meter on the leads in your '90 and see if it is a steady 12V or some varying voltage. I would think it functions the same as the earlier one. All you would need is a 12v source in the engine compartment that is hot when the key is in the run position.
Since I already had SSI's, I went with the heat and exhaust back dating. I get plenty of hot air from this setup. It blows air continuously through the exhaust shroud, depending on rpm since it uses the engine fan. It also uncluttered the engine compartment. Not to mention the cost of the blower if the motor burns out, which I've read about in the Forum. Also, I sold the blower that came with my '86 engine along with the A/C components for a few dollars toward the conversion.
