3 prong switch to 5 prong ignition switches

[Brian1045 28]

I'm going to give up on trying to find a 3 pronged ignition switch. What 2 prongs will I not use by switching over to the newer universal 5 pronged switches. Or better yet....since they are labeled differently what letters or tabs are the same on the 2 switches?

Is the "I" the same as the "M", "L"or "G" ??

3 pronged is labeled B-S-I

5 pronged is labeled L-S-G-M-B

You can't directly substitute a newer 5 prong ignition switch for the old 3 prong switch. The old switch was rated at much higher amps so power from the battery could be sent directly through the switch to the starter motor.

If you use a 5 prong switch you will also need to install a relay. (solenoid)

Did you contact "Sarge" about information on the original style switches he had found?

I'm glad you cleared that up. No wonder I couldn't get juice to the right spots. I thought I was losing it. I'll contact Sarge right away. I'm also watching one on ebay. Thanks TT.
