Knock Sensor Conversion - Re: [TECH] 3a dyno in and I amdisappointed, sorta...

[txrocco at sbcglobal.net (Patrick Bureau)]

dont waste time with the TT JH-> 3a distributor plate its not worth it , get a 3a/aba distributor (you will not regret it I swear it on my parents head)
 
I had trouble like no one when I did the JH distributor with adaptor plate, slap a aba distributor and you will have a smooth operating engine.

Hi guys, I have been reading this discussion with great interest since I
have an ABA swap in the works for my '85 8V Scirocco. I am keeping my JH
head and plan on converting to KS ignition. I purchased the conversion parts
for plugging the extra holes in the block and the distributor gear from TT,
but have not bought the KS parts yet. I have looked around the web including
the DriversFound site, but I am not totally clear on all the parts I need:

CIS-E distributor
Knock Senor
KS Control Unit
Wiring
TB Switch

I think I keep my old CIS control box, but not sure.
Any other sources on this subject?
Thanks,
Rob
