Has anyone looked further into installing the relay earlier in the circuit as suggested at the beginning of this thread by @NeverFinis ? Is that a feasible alternative (IDK)?
You mean the load source for the relay? I'm talking about offering an add-on to power from the battery. There's no other viable source under the dash.
Imo, if the wiring in an 80 is struggling to deliver the pixies to the power window relay, its not going to be solved by moving the load power one step closer to the battery, such as the interior fuse block. The problem is corrosion and/or missing wires (grounds).
I've been pretty intimate with the underdash wiring in a lot of 80's and something I've noted that's relevant to this discussion is even the ones with evidence of lots of water damage (Like every connector is full of green corrosion, rust streaks and flaky corrosion behind the kick panels) still seem to get full power to the window rocket fine. So my suspicion is the handful not getting enough pixies are suffering from issues nearer the battery-
Bad grounds, bad fusible links, heavy corrosion or??
What I have in mind seems simple.
The Window rocket rocket would get a two terminal connector added to the load wire after the relay plug. It would ship with a jumper connector plugged in to power windows from the power window circuit.
If someone finds their 80 has wiring that won't supply the necessary pixies they can buy the battery harness and it would plug in place of the jumper harness, then route load power from the battery.
If someone wants to DIY it just cut the orange wire off the plug and run it to battery+ with a 30 amp fuse and 10g wire. Run a 10g ground wire as well.
I don't believe this is a big issue. I'm just not a "it's good enough" kinda guy.
Thank you all for the feedback.
