Hey guys im after a bit of info on these guages, I have a Blitz boost gauge and a Blitz EGT guage which i know il need an exhaust probe jobby for, but its the other wiring involved do i need harnesses or can they be retro fitted? Am i right in thinking thinking the supra's ecu has a boost sensor? if so can i wire into that for the boost pressure? heres a couple of pics of the gauges and wiring,image

The red, orange and yellow will between them represent permanent (memory) power (red); ignition power (orange - for the functioning of the main electronic component of the gauge) and the last one (yellow) will be dedicated to the back-light. Black is negative.

 

The 4 individual wires with connectors were obviously cut to make fitment easy.

so will those marry up with a certain set of wires heading in the ecu/ignition? tbh im not the best at wiring/electrics, it took me 1 and a half hours too wire in my new washer pump bottle today and that was only two wires lol

Nooooooooo? Stay away from the ECU. If you don't know what you're doing down there then you'll make a right pigs ear of it mate. The wire colours are only significant to the Blitz unit so that you can tell what does what.

 

You need to know where you want to place the gauge and then plumb the wires in to a local/convenient power source. You can take the permanent power from the ignition feed-in wire or the clock while you will need to test the other wires to see if they run a current before or after the ignition is applied.

 

Do you have the rest of the gear to go with the actual gauge?
