What all is needed to repin 98 Vette auto harness to 99-up?

[GrannySShifting]

Anyone done this before?

[groundczero]

Yes just finished not that hard, but getting the tune switched over it giving me problems.

ANy issue like fuel sending unit not reading right, etc?

[GrannySShifting]

If you had to guess time on repinning what would it be?

Need 99-up connectors, cheapest way to get them?

[Howes]

junk yard prolly still plugged in to the ecm you need.....at least that's how lkq operates around here a lot of times.

Pricey though...almost $120.. for a complete set

I bought my ecu pins from Mouser and was happy with them, but I didn't see the connectors on their site

[Howes]

mouser is a great terminal source.

[GrannySShifting]

I just thought about this. Guy plugged in a 99 vette harness and ECU so the damn pcm pin side is fine. The pinouts I actually need to look at is the engine to chassis harness interface!
