if your set on rewiring i would do as reaper_mobb is doing do it your self (cheap) and just make your way forward, that way ya know what wire goes to what which will save time later on.
i will be rewiring a majority of my ta22, due to moving battery to boot, mice ate wires, 2 looms cut and shut, fuse box relocated to underdash/glove box, adding extra relays, gauges etc.
don't do it unless its needed in my opinion.
