I have wired up 3 EFI 5L commodores from scratch now, by modifying the original engine loom. VB-VS there is bugger all difference only the edits on the ECM to remove boldy control module & security locks. VT was a little more work with the secquential injection but even that wasnt too much hassle.

I now can have one wired up in under a day from scratch, it is a bitch of a job, including cutting holes int he VB-VH firewalls for the loom to go through and VK-VL removing the original engine loom and replacing the V8 one, mounting the fusebox out of the VN-VS and connecting up the accessories.
