Turn Signal Relay
 

This may be old news, did a search and saw nothing about it.

If you would like to save $25 when your turn signal relay goes out, a 4 prong relay for a '68-'70 VW (pretty much whatever model you care to name) is $10 instead of $35. Same relay for a 914, 911, 912, 930 made from '65 to either '84 or '89. You just have to remove a little metal tab from it, which I did by taking the head of the rivet securing it with needle nose pliers. It no doubt would cost you 5-10 hp using a VW relay in a P-mobile, but c'est la vie

That is all.
