The plan for modifying the instrument cluster takes shape. A red LED is going to be fitted in the warning light area to indicate a brake fail situation. This will be actuated by a switch under the dash. The rev light and yellowbox can be fitted into the instrument cluster loom. There isn't really room in the cluster itself and I don't want to start cutting PCB tracks. I decided to fit the yellowbox as I'm going into the loom anyway for the revlight. I could leave both of them out to fit later but we have to have some electronic toys. Fitting the rev light indicator will have to wait until I have an aeroscreen as I intend it to be (sort of) a head up display. Going to need a little more spirawrap for the loom modifications but I may try to get some smaller stuff. The instrument panel lamps are T-5 but I can't find any LED replacements yet.
Soon time to get dremelling :-))
