Question on boost sensor/sender location for Defi Link BF gauge, where is the best location, near the inlet manifold/plenum or at the boost controller module which is in the cabin, I have the APS TT installed.

 

As a rule of thumb, always tap the vaccum source at the plenum. If the front nipple on the plenum is already being used, you can simply add a T to it.

 

just like gq said, thats what i did, ran the hose through the firewall, and it's completely invisible the entire way through the car, and under the hood it is wrapped around by the battery and down by the plenum, simple T did the trick, it came with the defi boost gauge.

 

Thanks all, that's what I have done, T adapter at the plenum, mounted sensor/sender close by, around 6" of hose then ran the wire into the cabin to the Link Controller II, now all I need is where to power it from as there are 4 wires, red for constant 12v power, orange for power with ignition on, white for power when lights on and black wire for ground, any suggestions ?

Thanks
