R32 Gtr Single Or Dual Ignition?

[Sydneyactionman]

I’m in the process of installing a Boost Controller / Turbo Timer / Boost Gauge. I need to know if my 1990 R32 GTR has a Single or Dual ignition wires.

I have attached the best photos from the installation guide & it’s all the info I have. I’m stuck on where a few wires go if any one can help?

I’m guessing it’s a single ignition so I’m going to following the instructions for the single ignition set up.

I’m stuck on the following wires

The wire that goes between the relay terminal 86 & the Parking brake. Do I join a wire from the terminal to the hand break switch or do I cut the hand break wire & wire that to the terminal on the relay. Basically I need to know if it's wired in series or parallel. I'm guessing it's parallel & it's just to get an earth when the hand brake is applied?

The Yellow wire "switches the unit on & off" & is wired to the ignition this wire I'm really not sure about. Does it go to the ignition switch if so where on the switch. Or can any positive power that comes on with the ignition like the cigarette + be ok?

The Red +12VDC provides power. This wire needs to go to Battery positive does this mean it must be wired directly to the + terminal on the battery so it’s always on or can I wire it to a positive such at the cigarette lighter +

Any help would be much appreciated?
