So far this week its been nothing but wiring. Most has been spent on the CRZ getting the min harness in order the rest has been a gauge install on Brians carbon monster.
The main harness on a CRZ is an odd one. The ECU lives in the engine bay on this chassis so in turn half of the main harness is inside and the other is in the engine bay. The driver side headlight harness is also integrated in to the engine bay side of the main harness. This makes doing any sort of wire tuck a difficult task but still doable. As you can imagine this took quite a bit of cutting and splicing to make happen.
In our case we used a Wireworx engine harness with quick disconnect so this made the tuck process much easier but the main harness still needed extensive work to be able to accomplish a proper wire tuck. In using the WW harness it put the B and C ecu plugs inside along with the main harness interface plug. But the ecu A plug was still on the main harness in the bay a long with the C126 tower plug needed to be wired to the WW interface plug. So both of these plugs had to be moved all the way back through the harness to the firewall side. And while I was at it I moved all the AC plugs, SRS plugs and anything else we didnt need.
The result the engine bay side of the main harness is now thinner and has only the needed plugs for the new setup. And everything on the interior side is now where it needs to be to mount the ecu inside and do the proper interface into the WW harness.
Also installed the Innovative gauges on Brians carbon monster. Now.....time for pics.

Everything south of the blue tape represents the engine bay side of the main harness. Everything north represents interior side.
A closeup of the engine bay portion.
The white cables provide power to the electric PS setup, the interior fuse box and it used to provide power to the starter. Now it will Be inside and the former starter terminal will now provide power to the alternator. The stater now gets its power strait from the battery that is located in the trunk.
The rolled up bundle of wires are the ac wires we are no longer using. I didnt want to delete them permanently in case he wanted to get ac back so I just moved them to the interior.

This portion was the original interior portion. Consist of dash interface, fuse box,/PS/pedal switch plugs, relays etc.
This is the ecu plug and the c126 I will be cutting off and re pinning for a different plug.
The backside of the Wireworx engine harness. A long with a male connector and pins for the main harness interface plug I have to wire. A long with the B and C ecu plugs.
Brian's gauges.
