i have a couple nice mechanical gauges i would like to hook up (oil, water). the hole in the fire wall is all used up (next to the brake booster) with my wide band wires and does not have any room left to to run the mechanical water sensor through. before i do it my way does anybody know of a through hole that i could use to get the sensor through? 81 malibu btw. hate to get the hole saw out so i hope there is a possible hole somewhere in the firewall i could use. thanks

Run then through the speedometer cable hole, just open the rubber gromet hole that is already there up a little bit

You can always open the hole up a little bit more using a step drill bit.

thats the one thats packed full of wide band wires and a couple other 14 ga. wires along with the speedo cable. would have to unhook all of them before i could get any kind of burr or bit in to open it up. i may have to do that if nothing else comes up. thanks for the reply.
