Hey everyone. So I just placed my order for a set of Ignitech igniters for my Sabre. I noticed the Sabre (1982) has two identical TID12-04 Hitachi units, but the interceptor has one TID12-13 unit, and a larger black box with a red plug, what’s the difference between the bigger and smaller boxes? Can a single unit replace both or does the larger box have a different function? I was told 83 and up have rev limiters, but my dads 83 Sabre has the same two TID12-04 boxes, so I’m not sure what’s what on these.
