Default Is it safe to tap ECU wires??

How safe is to tap ECU wires, and what is the best way to do it??? Are those clamps bad for the wires. Can this connectors damage the wires???

Also is the ECU affected by tapping wires like A/F and knock sensor.

Also what can be done if you damage a wire close to teh ECU, can it be fixed??

don't tap the ECU A/F wire, there is NO good reason to ever touch that one. ignore whatever your turbo timer or A/F gauge tells you, do NOT touch that wire!

(and yes, people have reported all kinds of problems from tapping both... if you tap the knock sensor it reduces the sensitivity the ecu has regarding knock)

If you already tap it, removing the tap and putting electrical tape, would the resistance still is affected?

as long as it wasn't mostly severed it should be fine.
