Trying to dial my timing in with the skills I have but I have none so how about some input from the fsj guru's. I see the tach input connection on the coil but that makes me wonder even more questions so my question is what type of tach do I need for tuning this rig and how do I use it.
What kind of tach do you have and how do you hook it up?

I use a simple hand held dwell/tach. Have 1 for many years and another one that came in an Equus Tune Up Kit I bought at Harbor Freight. Sat for a long time until I got this Waggy. Simply connect battery clamp and coil (dist/-) clamp with an adapter - I use a paper clip - and thats it. I also block the wheels because 650 rpm in drive can override a weak/out of adjustment parking brake easy. On my 91 Montero I can access the computer trouble codes with the dwell/tach.Currently without

I can attest to both tach solutions for tuning, either a cheap dash-mounted unit or a handheld tach/dwell meter. I prefer the handheld version because it's right in the engine bay and isn't permanent (I used to have a Sunpro tach in my '89 GW and it looked terribly out of place).

I go for the low cost Sunpro style as well. Actually bought a spare just for under hood work.
The regular one is mounted to the steering column just like most do (glove box works too though). The second one I fitted with alligator clips (from radio shack) on the power, ground, and signal wires so I can use it as a hand held unit under the hood.Mike Wood
