1G(91-94) IACV in a 90 Harness


Our custom harnesses are designed to simplify your vehicle wiring. They are made with automotive grade wiring, OEM connectors and terminals, and quality construction material/methods that meet or exceed OEM spec. The goal is simple: buy the harness, install it, then not have to think about it again.

This harness is designed to allow the 91-94 style 1G IAC to plug in to the 1990 style harness. The 91-94 style IACV has a connector built in, the 90 IACV has a pigtail coming out of the IACV. This harness plugs into the later style IACV, and is long enough to plug back into the 1990 harness. It is built as shown below, with the connector, 9 inches of wire, and the protective sleeving shown. The sleeving is designed to protect against abrasion and other underhood problems. The sleeve is heatshrinked at both ends to prevent fraying.
