Adding Sensors to Haltech PNP Hanress

I have an Elite 2000 with a pnp wiring loom and i am starting the process of wiring in some sensors.

Do i unpin a plug on the adapter side and crimp it to the sensor, or do i cut and recrimp with three wires?

Will the Sensorground require similar work?

2nd question, where do i get my power supply? 5v and 12V. Do i use plug A9 for 5v and A13 for 12v, or should i splice in to the radio wire for example?

I think this is missing in the wiring course.

I have this Ecu and adapter.

Thx for your help!

Q: Do I unpin a plug on the adapter side and crimp it to the sensor, or do I cut and crimp with three wires?

A: It is up to you where you wish to repin to it makes no difference to the final job I would do what looks the best.

Q: Will the Sensor ground require similar work?

A: it can be spiced into any other sensor ground wire like map sensor or tps, avoid trigger sensor ground,

Q: Where do I get my power supply? 5v

A: you can splice into any 5 volt sensor wire,

A:12V. should come from an ignition sourced relay
