Thunderbolt iv pickup

[midnightrider1818]

Hello all. Gonna replace the pickup in my distributor. Got a thunderbolt iv in the girl. Doing a complete tune up on her. Had cliff rebuild my quadrabog and bought a new cap rotor plugs and wires. Pulled cap off and original pickup looks rough so I thought might as well do that now. Problem is mine is the old nut type and the new one looks to be all integrated. You guys us butt connectors or does it come with the harness to adapt to the new bullet style. Question is how did you guys do it

New unit comes with short adapter leads...

This is what the kit looks like...

Yep, easy job. plug and play. That is...if your rotor isn't stuck on there! I had to cut and carefully split my rotor to get it off. Apparently they are installed with some type of lock-tite. Most people reinstall without the lock-tite.
Everything you need is in the kit. My old one was grounded through the mounting screws. The new one had a separate external ground wire which I had to ground to the engine.
With the new pick-up ignition module, cap, rotor, plugs and ignition wires, my 4.3 ran smooth! Nothing like a good tune-up!

Ok I see the kit but I must be missing something. I'm assuming I would need to use the adapter leads
my question is though now that the new unit doesnt have posts how do the ring terminals connect ??

I see what you're saying. Mine didn't have posts like that. Maybe because mine is a Thunderbolt V. Mine had wires sticking out with bullet connectors that plugged right in. So, I guess what you have from your Thunderbolt IV box is two wires with ring terminals on them. So, you either need a different module or have to change those rings to bullet type. Sorry, I don't know. But hang on...achris is a genius on these matters and will chime in.

The kit also includes a couple of nuts and bolts and heat shrink tubing. You use the nuts and bolts to connect the short adapters to the white/red and the white/green leads coming from the module. Then slide the heat shrink on and shrink it down. You now have the sensor leads with bullet connectors on the ends instead of rings... Install the sensor and plug the bullets in...
