Some of this is geared towards a specific car, but can be applied to whatever you're harness/car is

I would suggest dumping the 98 PCM and sourcing a 99-04 unit. Info and tuning is much more available for the later

These are all the 98 connectors, you'll need to use all the power and grounds obviously but some of them such as the pink ones need power when in crank position also. In the c220 connector the black/white wire is used for fuel pump relay ground.

Keep in mind that these swaps can get crazy expensive and will most likely go over budget.

My $2000 planned swap has doubled in cost so far and the motor isn't even in the car yet. Just be aware, because if you already spent the cash on a 98 harness and people are suggesting to buy a 99-up harness there is an added cost not planned on for example.

It's the little things that add up, the engines are cheap.

I used lt1swap.com for the info needed to re-work my harness, it took a whole day but it turned out nice.

He doesnt need to dump the 98 harness to convert. Several threads about the change are found in the search feature. Its not overly difficult, just time consuming much like all harness work in general
