Re: Installed 700R4 - Hook Up Lockup or not?

I would install it. I would use both the external vacuum and brake switches and internal 4th gear switch so that it only locks if you are 1) in 4th gear 2) no on the brakes and 3) have intake vacuum (not accelerating). If any of these conditions is not met it unlocks. Simple.
