countryboy:
Frostheater kits come with very detailed instructions and pictures (and a bag of M&Ms). Anything more than changing the oil in a car is a challenge for me, and I found installing a Frostheater was very straightforward.
I would think the only differences between the manual and DSG kits are the shape of the mounting bracket and the lengths of coolant tubes. Try emailing Evan Frost (manufacturer, email on his
website) if you have questions beyond that.
Good luck!
