Default Tach cable

Do you have to remove half the dash panel to replace the tach cable ?

you will have to get behind the driver panel to unclip it from the tach which will involve dropping the steering column some to be able to get behind it and around all the wires etc.

It might be easier, but it can be done without removing the dash or steering column. Remember to disconnect the battery. You could encounter some powered connections while fishing around. It takes a bit of an acrobatic position to get your hand up behind the instrument panel; and, you can't really see what you are doing. Even though I am 6'2" tall and 65 years old, I can lay my back on the front seat and head up against the pedals to work under the dash. My tilt wheel helps. For just the tach cable such an extreme position may not be required. If I remember correctly, you push in (toward the face of the tach) on the retainer to release the cable from the tach. Then it is a matter of carefully threading it through the firewall to avoid pulling vacuum hoses or electrical connections off. Be slow and cautious. My experience is that fixing one thing often results in damage and repair of an adjacent thing, etc., etc. Happy fishing and enjoy the ride.

.... Bin there, done that. It is a bit tight, but can be done. Just becareful of all the wires around. Just get comfortable under there, take your time and go for it.

Our experience of adjacent parts breaking is correct. For every one thing I repair atleast two more new problems arise.

I replaced my tach cable with the dash intact. It is difficult, but possible.

The trickiest item was feeding the square tach drive into the back of the tach, then seating the cable. My way around that was to have my wife push the cable toward me from the engine compartment, confirm it is seated properly, then have her feed the sheathing to me until I get it clipped. Actually worked pretty well, once I figured it out.

Push on the "Black" clip while a helper pulls the cable out from under the hood.
