16V Scirocco wiring guru needed...
It's a typical 4-prong relay harness. Terminal 30 goes to battery (fused
30 amp TYVM) terminal 85 to ground, 86 to the low-speed terminal on the
thermo-switch, and terminal 87 goes to the fan. Terminal 86 may be a
double connector, with one lead tied to the A/C. Terminal 85 and 86 may
be reversed, but it matters not in the grander scheme of things.
(TYVM = thank you very much)
Hope this helps.
