Due to the age of our cars and high heat conditions under the hood, the original connectors on the engine wiring harness tend to break to pieces and cause all sorts of issues including hesitation, running on less than 6 cylinders, and even stalling. We usually suggest taking the opportunity to change this harness if the engine is out of the car on any Z32 with over 100,000 miles.
This EFI Harness, although built for '91 Non Turbo models, can be used with any '90 - '92 Non Turbo equipped with a Manual Transmission.
In the event that this particular harness is out of stock we may choose to substitute with any of the part numbers below.
This listing is for one new Nissan OEM Part.
Often the 20+ Year old Alternator to Transmission harness is brittle and corroded causing inoperative or inacurate readings for transmission sensors. This harness also supports the alternator and starter signal circuits, problems with this harness can leave you stranded. Easily replace it while replacing your EFI harness! Z1 now offers a replacement harness for much less than the Nissan counterpart, add it as an option with the transmission and save even more!
Even more important than the Alternator to transmission harness is replacing the Knock sensor subharness when you have the opportunity. This harness is exposed to the worst heat cycling and condensation in the engine bay and often suffers the most, often leading to poor running conditions or inaccurate knock readings. Choose below to add a new Z1 Upgraded knock sensor harness and/or knock sensor with your EFI harness for a discounted price and it ships for free with your EFI harness.
