The person doing the installation must have the skill and experience to first remove the entire dash.
When that is done, all the factory AC parts, ducts, wiring and other items need to be removed from the car and dash.
The firewall opening will need to be trimmed at the top edge for clearance of the Gen IV unit to be bolted in place.
All the under dash AC and heater hoses are crimped and pre-assembled on the Gen IV so no plumbing is required there.
Ducting and dash adapters supplied will then be installed, and the new VA electronic control unit is mounted in place of the stock one.
Wiring is basically plug-and-play with the small VA control box, and switched power is the only connection needed under the dash. One control wire is run to the engine compartment for compressor switching.
The units installed in the field have been completed with no issues, and we are always available for tech help if needed.
The compressor, lines and other items under the hood vary depending on the engine and customer's preferences, as we do supply various parts if and when requested.
