Up for sale is a rebuilt, remanufactured and upgraded Engine harness that directly fits all 1986-1988 Pontiac Firebirds and Chevy Camaro's with the TPI fuel injected motor. It can be made to fit 1985 and 1989 as well, with minor changes. In addition this can be used directly with the MAF system only. MAP metered fuel injection would require a different harness. This harness has been modified with upgraded power distribution and has all engine related relays and fuses centered in a single fuse/relay center which would take the place of thhe firewall relays on the drivers side. It has been tested on a car and works and does all that it is supposed to do. The grounds for the heads on the block have all been moved to the drivers side head so that install is much easier. All power wires coming from the starter have been eliminated and thus the fusible links which are tedious to replace have been eliminated, fuses are in their places.  Most plastic connectors which were missing the locking tang were replaced with the exception of the MAF connector, but virtually all other connectors are new. The replacement MAF connector is included in the sale. The entire Injector harness was replaced, there are no additional splices that what came from the factory, if anything there are less. In addition, any compromised wires have been replaced, typicaslly they were found near the exhaust or other hot areas. The harness was rewrapped in techflex and plastic loom, for the most part techflex was used, but in some cases plastic loom was added for extra protection. By the starter, there is a heat shield surrounding the wires, as it gets hot in that area. Install is straight forward. 

Please message if interested or if you would like something similar done to your harness. The original one is a pain to remove, this one stakes about an hour to install and route.
