Going to run test wires from Boost sensor to Dash mounted volt meter to check output voltage through idle which should be about 1.9v to foot down, overtaking mode. There's 4 wires to sensor, anyone got wiring diagram as to wires to test on.

 

tfb usually has the spark chasing diagrams goggsy, no doubt hell spot this post and help when he has time [he works night's mate].

 

it's a pressure and temp sensor

1 DB GND
2 DB/LG Temp sensor signal
3 LB/PK +5V reference voltage
4 DB/YL Boost signal

Regards
Richard

 

Good just got to add offtake connectors to these wires. I used to use bullet connectors the old soldiered type, I now use Crimp bullets, male and female. Not very elegant some would say seeing these atop engine. Anyone got ideas for connectors to the 4 wires. Could trace them back but all wrapped in tape.

 

Some use glue shrink I use cheap heat shrink cut to size - after - first soldering the wires together properly old school, the joint never comes apart and never ever suffers from condensate[s]. A more expensive version is soldered shrink. Best of luck goggs !
