Getting stuck into the wiring over the weekend and as the original harness was in reasonable condition I see no reason not to re-install it but I need to make some changes to improve reliability and to include some additional items (EFI, EPAS etc). The idea is to install a new fuse / relay box inside the car as I have removed the original fuse box from the engine bay. I will integrate the new fuse box and relays into the original harness via 2 8 pin connectors. I have incorporated 5 relays which are all controlled via the Haltech Elite 1500 ECU in an effort to remove the electrical loads from the OEM switchgear.
- Fuel Pump - control the in tank fuel pump.
- Ignition - everything that originally operated via the IGN switch in the ON position. Have split the output into two fused circuits as per the original layout.
- Engine fan - obvious.
- ECR - Injectors and Ignition control.
- Starter - Starter motor control (can set the starter to automatically disengage when a particular engine speed is reached or prevent starter operation under predetermined parameters).
Overall there are now 15 fuses throughout the car - 10 mounted in the new fuse box, 2 headlamp (dipped and hi beam), 1 demist, 1 horn, 1 starter and a 40A circuit breaker for the EPAS unit. I have also used the OEM wiring within the new fuse box where possible to retain some relevance to the original schematics. A separate dual relay under in the engine bay will operate the headlamps and another will operate the horn. I will continue to use the original demister relay as I see no need to change it. The starter relay will use a fuse mounted on the relay as I ran out of fuses! So, hoping this resolves the issue of fuse reliability and prevent the melting of the headlamp switches

.Also removed the old cluster connector and added an aftermarket item as I have many more inputs etc to run the additional features in the updated gauge cluster.
