Thanks!, will check on the hum to see if it's coming from where you suggested. Luckily I did keep the dimmer and hazard switches and I think all my lights work with the exception of the license plate lights but that's probably just the bulbs.
I've been super careful pulling the loom apart and grounding everything, working meticulously to follow and remove any plugs I don't need through the loom to fuses etc and everything has been going beautifully until all of a sudden my right indicator is now blinking at 2x the rate and if I start the car and turn my right indicator on the car stalls.
I've doubled back and reconnected what I took out since my last successful test but still no joy.
I'm thinking a bad ground but I've revisited them a good half dozen times.
Has anyone encountered this gremlin while picking apart the wiring loom?

Are all 3 indicators on the r/h side illuminating? (i.e front/rear and side repeater? (if one is out then the reduction in load will cause the others to flash twice as fast.) Is the hazard warning switch connected up and operating correctly?
I know you say you have checked all earth connections - but have you checked the main earth to the P.P.F and remembered to re-fit/replace the braided earth between the engine/bellhousing and the Replicar chassis?
Admittedly, though, it does sound like a short somewhere. First simple test would be to see if the problem is a faulty bulb - so does the problem still occur if you remove the R/H indicator bulbs and then operate the indicator stalk?
Did you check that all circuits (inc. starting/running the engine) still worked each time you removed a wire from the loom? (if so, temporarily replace the last one removed and see if that helps.
I've been cheating regarding the earths and bypassed the PPF entirely (for now). I've run a line from the battery negative cable earth to the braided line on the bell housing and then run earths down to that braided line.
I've clearly removed a wire from something I should not have is my guess. The EGR valve next to the "boost" valve is also clicking in sync with the RH indicator.
The car starts and runs fine. My approach was to remove one plug at a time by tracing all the wires for that plug to either a connection on another wire or another connector. None of the wires I have removed "connect" to anything else or bridge so I assumed I was safe. (clearly I was wrong).
After a little R&R it's time to get back at it and all extraneous wiring has been removed and it's time to re-tape the loom.
I am left with 2 unaccounted plugs, the first was for the optional fog lights which I'll keep should I want to add them.
The second is a "spare" 2nd rear O2 sensor. This is a California emissions add-on for a second catalytic converter so I'm going to tape that up to the main loom in case the car end up in CA before the engine gets swapped for something more exotic (plan is to replace the tired 4-pot with a build AAN inline 5 with VEMS after it hits the road.)
I'll eventually post an annotated copy of the wiring diagram with things I deleted highlighted for others to consider.
Once re-taped/shrouded I'll post some photos and it looks like a couple of wires will need to be extended (eg: main headlights)
