Hey all. I wasn't sure which forum to stick this in so if this breaks any rules, sorry. I'll move/delete if necessary. I've got the Delco Voyager EST Distributer set up on my Holley carbed Ramjet 350 and i'm looking to check base/initial timing. As i understand it correctly, the 4 pin plug on the ignition module needs the "special" adapter plugged into it so that it shuts off the timing advance so that base/initial timing can be set correctly. I don't have that "special" adapter but do have a regular GM plug that fits with all 4 wires available. Could someone please let me know which 2 pins are jumped together and which pin gets the 12v? The letters on the plug of the ignition module are Left to Right, clipside are - GBRE. I did set it @ 30deg while fully advanced at about 2800rpm and it does run ok (other than not being able to go beyond 3k rpm on the water all of the sudden!!) but would still like to make sure it's around 8-10deg @ idle. Thanks in advance.

This should cover it.

Thanks Don and thanks for moving this post into the correct place. I actually did find that poking around yesterday but was afraid it was for the Volvo and possibly different jumpers. Appreciate it much.
