TR4/4A Where do the ground straps connect


Jedi Trainee
I guess the cable ground from the battery goes to the chassis somewhere. Then there must be a strap that joins the engine block to the chassis.
Can someone enlighten me.
I think I can figure out the grounds on the harness, behind the dashboard and in the trunk (boot).
Thanks in advance

There is a wide braided cable from the battery to the firewall. The body-to-engine ground goes (as I recall) from the left hand motor mount to one of the bolts holding the timing cover.

There is also small braided ground connection from the steering rack to the rack mount to allow the horn to function. Also similar ground wires that 'jumper' around each rubber flex connection on the steering column.

I have photos - which would be very helpful - but they are on Photobucket who now charges something like $400 for you to look at them.

Thanks George
I got the horn grounds on already but I was concerned that the starter current would ground up some wire that was not designed to handle it. I remember when I stripped the car down that there was a ground cable going to chassis but someone could have changed it. What I was most concerned was the engine to chassis ground strap. I don't recollect anything bolted to the timing cover but that would make sense. That is from lower part of motor mount to timing chain cover.
A picture is worth a thousand words but not $400

Soooo, here is a pic of mine and this is where mine was. However, mine was grounded to a hole JUST behind the engine mount hole. Soooo, essentially the same part of the frame. But the other end was one bolt down from where the engine hoist bracket is. See pic..

Yeah, sorry about that. Was more showing where it attaches to the engine. The other end goes in the motor mount on the frame or in my case there was another hole right near there and I figured that was for the ground so I just used that.
