12v hot all the time, 12v ignition, check engine light wire (to dakota digital dash), speed sensor wire for ecu, two grounds, and fuel pump wire. I made it so the harness only has a few external wires to hook up. I fixed the harness using both wiring diagrams below.
ALDL DROID FOR FREE
The wiring harness that I got for free was pretty butchered a ball of wires when I got it. Using OSE12P I was able to use a MAP sensor on my 165 ECU which was originally a MAF ecu.
ALDL DROID CODE
Its modified version of the stock code with a bunch of unused or undesirable stuff taken out of the code. Such as: spark/fuel tables to 9600rpm, boost capable, wideband datalogging, flexable outputs for relays, etc. So OSE12P is the 808 code with a lot of improvements. The difference is that GM of Australia decided to a MAP sensor on the 808 ECU that we never saw here in the states. This is identical to our 165 ECU in the US. In Australia they have an ECU they call the 808. After some research into the ECU I came across what is called OSE12P. The ECU I got along with my intake was a 165 ECU the less desirable one. So your more likely to get one easier and for cheaper. MAF ECUs are the less desirable of the two ECUs. MAF sensors are bulky and expensive and require several additional relays. The 165 ECU uses a MAF sensor and the 730 is a MAP sensor. The third gen camaros came with two primary ECUs one a MAF ECU and one a MAP ECU. So I wanted to reuse the wiring harness and the original ECU that I got if that was possible. Its not an ultra cheap build but I did try to keep the price down. So I decided to take up the project of getting one working on an engine.
However I personally like the look of a TPI intake myself. I am aware that you can go out and buy an aftermarket TBI setup like the sniper EFI or FiTech. I have seen a few of these intakes showing up on craigslist over the past few years for cheap. I picked up a painted TPI intake with a ECU and butchered third gen camaro/firebird wiring harness for $200. The TPI intakes from 3rd gen camaros, firebirds, and corvettes have gotten way cheaper at least in my area. I have noticed a trend that has started to happen. As the LS engines have gotten more popular and as aftermarket fuel injection technology has progressed.
