They are not original and should not be necessary with an original GTR Tachometer and original points distributor.

 

Could the car have been fitted with an electronic ignition system that made it necessary to have those resistors to make the tacho work properly???

Maybe a V8 fitted at some stage?

It hasn't been on the road for twenty years , were they fitting them in the 90's ?

MSD units were around in the 80's as were the HEI ignitions in the Commodores & WB's. That said I don't think the installation of a HEI from a Blue or Black 6 would have required any resistors be fitted to the GTR tachometer trigger wire.

was just chatting to the sparky upgrading my loom only yesterdy actually on Hei.asked whether im going to run std points

or Hei...told him std but down the track i will change to electronic dissy.so he just put another pink wire through and terminal

all he said was the std points wire is a resistance wire and only gives the coil approx 8 volts which isnt suitable for Hei

Are they on the positive power feed to the tach or the signal wire from the dizzy?

30+ years of wiring being fiddled with throws up loads of "what were they thinking" moments.
This what was was "suplus" from my hatchback.

Hi TBM,

Who knows with a 40 y.o. car!..maybe the pink factory resistance wire in the coil circuit had an issue at some time..and this was someones way of trying to fix it??

p.s. thought the resistance wire was in the coil circuit, not the tacho circuit........but ?

 

p..s from where I have seen you drive the car (from pics) assume it goes just fine....and if the tacho also works fine...I'd be tempted to just leave it mate......unless you are looking for a challenge..lol
