72 LS5 TCS wiring question

[Mike E.]

I'm assuming that a 72 LS5 (4-speed, with air, if that makes any difference) does not use a TCS relay behind the tach. AIM LS5 p. A10 shows a "jumper strip" (view A) in that location. Am I reading that correctly? And exactly what is a 8905858 jumper strip?
Thanks!

Correct - does not use a relay.

The jumper is 2 prong and fits into the connector for the relay.
It is the two outer prongs (pretty sure).

Am I correct in assuming, although it looks like a more modern fuse, that it is not, and instead simply effects an electrical connection between the two wires it connects?

Mike,

I am not 100% sure.
It does not seem like it is a "fused link" type of jumper to me.

I am pretty sure you could just jumper the connect with wire and it would work just fine.

Hopefully someone with more technical knowledge will chome in on this ..

Mike that part is (was) just a shorting clip, the service manual wiring diagram doesn't really show enough detail to see exactly how it is used, it was onluyused on the LS5, per the service manual, looks like used in place of the TCS delay relay? Think of a stamped brass bar with an insulating coating in the center.
