painless harness and oem gauges.

I want to know how the painless harnes integrates with the oem gauges if at all. I have an 80 elky with a 95 z28 lt1 swap and the ss cluster. If I am looking at it right then the ecu wiring harness is totally independant of the gauge harness ( or maybe one or two wires have to be soldered to things like the temp gauge or altenator voltage), but I want to see who has a painless harness for this type of swap and how it went. are the gauges independant from the harness or is that part of the painless system, wiring up to the firewall where the oem cluster plugs in. it looks like the easiest place to put it is on the passenger firewall just in front of the blower fan. the drivers side just looks like a tight fit with the brake booster, steering column, etc.

thanks for the help.

You should be OK with you tach, oil pressure, volt, and fuel guages. The wiring harness should hook right into those guages. One thing to be aware of, is you transmission. From 1993, and up, the speedometer runs off of an electronic vss from the transmission through the computer, then to the speedometer. If you are running a 1993 or newer transmission, you will need to get an electronic speedometer, or a vss converter. You can get the speedometer from just about anywhere. If you decide to go with the vss converter and keep your manual speedometer, you can get the converter from http://www.jagsthatrun.com/.

I went ahead and got the whole cluster from nordskog. It is pricey, but, worth it, and is an easy install.

When you remove your original engine and computer, just pull the wiring harness through the firewall into the engine bay, and follow the wires from there. You will see that the engine wiring harness is pretty much separate from the wiring harness that runs everything else in your car. When you put in the new electronics, you will see that you are pretty much replacing what came out with the old wiring harness.

Another F.Y.I. If you are running an overdrive transmission, you will need to get you driveshaft shortened as well.

the tranny is electronic, and the driveshaft has been shortened. I have looked at the different cable converters and I am in the process of working on something that may let me swap out the cable speedo for an electronic one. I will read that link and see what info I might be able to use to make it easier, so thanks.

The original motor was carb'd so the only thing going through the firewall is for the instrument cluster, and there is no under dash fuse panel. the harness that came off the old motor just peeled off of a few sensors and laid to the side, the new harness with the ecu would need a few splices to hook up to the instrument cluster, and a whole lot of splices to solder the fuse panel to the ecu harness, thus I am looking to painless to save me a few days of wire chasing and heat shrinking.

the original harness looks like it plugs into a big cannon plug at the firewall so fishing it out I don't think will happen, but if I can just tap onto those few wires with the painless then I am set. So basically the painless harness takes care of the tranny, motor, ecu, and fuse panel. does it include the starter ( I wouldn't think so except for the signal wire) and does it include the wiring for the fans and the temp that they come on at?

thanks
