I have no experience with this kit but some people install the "Big Seven battery cable kit" which includes wiring going to your starter. I realize the big seven kit is roughly 3 times the cost of this ama zon hotshot kit. There are a few threads around of people making their own big seven kit. I would think that just replacing the battery negative to frame and engine ground and starter wiring would be a big step in the right direction if your having starter problems due to old wiring.

 

I was experiencing intermittent no starts (no crank) several years ago. Previously I had used a similar set up on an old car (1972 Opel) and the relay worked fantastic. I guess the old ignition switch just could not put out sufficient voltage. Since it worked so well previously I ordered the painless kit for my 2000 Tacoma 3RZ and that is still working today. My starter did go out this year and I replaced it with rebuilt OE from Rock Auto (I understand you can just get a repair kit to fix the OE starters but a PO had already replaced original with aftermarket at some point.) I am not a mechanic or electrician but the theory on the relay (Painless Kit) is that you only need a signal from your switch wiring as opposed to enough power to actually start the truck. I aasume it is possible the Toyota already uses a relay and maybe I was just lucky that I never had a starting problem again (until years later when starter gave out.) To me it was worth it.
