Well I tried the blink tool... but it was a no go for me.
At Radio Shack, I couldn't find the banana plug set (274-271c), so I bought 274-721c, assuming maybe the original was just a typo (2-7, 7-2).
Anyway, the banana plug set is way too big to fit into my connectors in the 95 C280. I don't know if I have the wrong banana plug set or if the system has different size openings?
Now for question two... you say to plug black into number 1, and red into number 7... which hole is one, and which is 7?
(If it'll work at all on my C280!) ...I can already get codes (climate control) via the PBU.... will I be able to pull ABS, SRS, or other codes, besides just the Climate Control codes? If no.. then my work is pointless!
