How can I check all the wires if they are not plugged and the motor isn't running? If I have a leak or something, I wouldn't notice.

I actually find it WAY easier to start from zero than trying to modify an original harness.
(Mind you, that's my own opinion and it heavily depend on your skill and how familiar you are with that kind of task)

The last one I have done: (my friend's 4AG swapped TA60)

It seems a pretty good job actually! Where did you sort all the plugs and connectors?

I'm not familiar at all, but I would like to give it a try. I have nothing to lose, except time and some money.

The other way to go is to go deep in the wallet: standalone ECU.

But I have to wait for another year to collect the proper money for a good aftermarket ECU and program it.
