AW11 and SW20 A/C Factory Denso Installation Library

Postby entrax » Thu Jun 14, 2018 3:37 pm

This is for cars that do not have A/C and you want to install A/C in the car as they did back when the car was new. For US cars, this is done at the factory, but for Canadian cars, it was a dealer-installed accessory kit. The wiring diagram for the A/C system is also at the end of the PDF.

This is for the SW20
Note:
    -The only difference between the factory piece and the dealer-install kit is that the 2 long pipes under the middle of the car are one-piece for factory, and two-piece for the kit to let you install it without removing the handbrake brackets under the car. Since a US car is practically the only place to get A/C pieces nowadays out of part-outs, this part of the installation can vary as of course you'd need to move the handbrake brackets to fit the one-piece long pipes.
    -Highly recommend to get a R134a compressor from a 94+ if used.

This is for the AW11

Thank you to:
