Where does TD tach cable pass through firewall/bulkhead

Post by Tom P » Mon Mar 13, 2017 8:09 pm

Trying to sort out how to route the tach cable from the generator to the tach on the dash of a US spec LHD car. For some reason it is not obvious to me! From online photos it would appear the cable routes behind the engine. Does it go through the trans tunnel cover or is there another hole there somewhere in the bulkhead? Thanks in advance. Tom

Car is making a little progress - my scruffy chicken coop find is cleaning up. My intent is to keep expenses on the car at a minimum (even leave the 1960's era Earl Scheib resale red paint job). Windshield was a mess, so off it went! Top fabric was missing and the bows were a mess... so off with those as well! It's only a handful of screws to put that all back on, and it all has to come off to restore properly anyway - so no worries. I had a proper set og grille slats in the barn and gave them an appropriate paint job. I'm a few weeks away from having a proper driver!

The tach cable on a TC goes right through the firewall into a hole almost directly aft of the generator, but I don't know about the TD.
By the way that grill looks nice and period. :thumbs:

OK. For some reason I am not seeing any obvious bulkhead holes there! THere is sometimes a TD at our local cars and coffee, but he was not there this morning so I could not get a hands-on view of another car. And all online engine bay photos are not close enough to see through the maze of items near the bulkhead as to where that cable definitively goes. I'll keep tryoing. THanks for the comment on the grille - I debated with myself for 2 weeks if I should paint it this way and I am really glad I did. Since this photo the car has received a set of 576SLR Lucas driving lights (my wiring project for today) and my late-40's-early-50's white racing helmet is in transit - to complete the period look!!! I have done all new cylinders, master, flex lines, and shoes, but bleeding is proving for some reason to be a real pain. I have no decent brakes at the moment. So, bleeding and rebleeding is on the weekend plan as well.

Tom:
It's my recollection it goes thru the larger of two holes in the left lower corner of the battery box.

Brian, EXCELLENT! Thank you!! :o)
I spent the whole day working on the TD - got the brakes adjusted properly and bled - even had a satisfying test drive. I will add the tach cable later in the week or next weekend. THank you!!!
