s13 sr harnes to s14

[zenki 95]

I have an s13 sr20det in s14 chassis, had a harness that worked but was pretty trashed. Now I have a s13 for s13sr converted harness that im trying to convert once more to s14. Seems the only trick is the dash plug and relay thats missing. Has anybody had any experience with this situation? This new harness I have is really clean and shielded so id like to save it.

If not I guess wiring specialties is a go
