did you do the engine wiring harness????....if so....how did you do it???.....n what you need to do????.....lmk....thanks...STY

 

Cut one wire at a time and extend it..... solder iron, solder, heat shrink.

 

Before I did it people said you needed to extend it 24-36" BS !
18" is perfect. I cut half the harness in the middle doing small groups of (non alike) wires at a time and did the other half of the harness by the ecu plug, this avoided a huge clump from the heat shrink. then bought 2 long usb cables to use to extend both knock sensors. This is needed because the usb is shielded.
thats it!

Or you can buy a plug and play extension I've seen online. for $180 i think

 

For 180 a plug and play extension would be worth the money.
