I think the best is to just add 2 new wires so you don't have to mess
around inside the wiring harness.

You should read the thread on Jeep CJ 258 acceleration issues.

Here are a couple good links on tweaking the 258's:

http://home.sprynet.com/~dale02/ignmods.htm

And before you attempt to mess with the mix, the mix must work so here
is a good link on that:

Before you start, a carb kit is only about $20.00 at CT and is easy to
put in. You really need that carb working or it will 'never' set
stable.

When you set the mix, you need to turn the screws 1/4 at a time with a
rev between each turn. When it starts to miss, back them out 1/4 turn
or just until the burble goes away. The 'sniffer' likes a slight
burble.
