hi all ... i recently bought a ct racing boost gauge brand new from ebay but instructions were missing .... so i am left with no option but to ask for help ,,,
Firstly whereabouts does the hose attach to under the bonnet. and i have four wires which i assume are for live, earth, and ???????. i no it seems a bit thick but the wires are not the normal colours , 1 black , 1 purple 1yellow and 1 orange ,,
please help if you can , thanks in advance

 

erm, what car is it going on?

the wires dont really make sense, its obviously mechanical as you have a hose.

all that leaves that is electronic is the back light, which would be 2 wires.

or am i missing something

 

I'm lost on the wires, as black and red would normally be -ve and +ve for the rear light, and the hose will tee-piece in with the boost vacuum hoses, i've the one that goes to the dump valve

 

got any pics of the guage or even the listing?? might help someone

 

You'll need some boost hose from the inlet manifold to the back of the guage. The rest will be power and ground, and one will need to be wired into the headlights to light up the guage.

Should of got one from Nomad IMO
