The easiest and quickest way to install your GM harness is to let HSC simplify it for you. During this process, all unnecessary circuits are removed, harness repairs completed, RX7 chassis connections are consolidated and labeled, OBDII port installed, and new coolant temp wires are added. This process drastically cuts the installation time, and combined with our technical support, we're yet to have any customers not be able to wire their car. This is highly recommended for those installers who have doubts about their electrical skills.
Manual to Automatic and Automatic to Manual transmission harness conversions are not included in the price. Typical surcharge is $100. All AC connections are controlled in the harness. You will have a single AC request wire from the dash.
