My S5 TII boost gauge on my stock tach does not work and it must have been hooked up to an after market gauge because I found this defi electronics in the engine bay and this plug wire was just hanging from my dash.



Is there a way I could buy defi gauge and is there a certain one? or should i see if i can splice the wires back into my tach? I'm running an Lt10S ECU thats currently set to stock.

I'm not as experienced with this stuff as i'ld like to be so any advice would helpful thanks

 

Well, there's no real way to buy only the gauge portion of a Defi unit unlessy ou bought it used, in which case you may be buying something that doesn't work, and would *probably* come with a sending unit anyways.

So, no that sender probably won't do you any good. If you need a boost gauge just buy another setup.

 

Ive bought standalone defi gauges before, just check ebay.
once you have the gauge going you wont need to worry about the stock gauge
