Figure 117. The valve covers are finished. The copper paint was removed from the LSX emblem, it was not turning out as well as hoped. We may revisit it in the future, but for now, the aluminum looks fine with the now black valve cover.

Figure 118. We are starting to assemble the wiring harness. Here, we are checking how the wires will route for the passenger side injectors and coils. In the factory harness, the pink wires for each group are spliced together up on the engine itself. For this unit, we are going to move the splices to the main trunk of wires that exit out the back and go up towards the PCM. Since the fuse block is going to be mounted near the PCM, this will give a good location for the pink wire connections. The brown wires in the coil connectors will also be spliced together in the main trunk.

Figure 119. The wires for each side coming out the back before being spliced and bundled together. All of this currently is mock-up so the harness can be measured for the sleeving that will go over it.

Figure 120. All the wires are routed to the back of the engine. The next step for the harness is to group the bundles together then start sleeving and splicing wires together. For instance, the pink wires in each coil group and in each inejector group will get spliced together down to one wire which then goes to the fuse block. Those 16 wires will be reduced down to 4 after splicing. After that is done, then the wires that go to the PCM connectors will be terminated and inserted into their respective connectors.
