TR2/3/3A TR3A Dash and Instrument Cluster Installation

Afternoon, I'm fast approaching the point that I'll be ready to install the dash and the instrument cluster. The wiring harness is wired to the instrument cluster. My question is: do I install the instrument cluster into the dash and then mount the two units in the dash position? Or do I mount the dash get secured and THEN mount the instrument cluster?
I'm asking this based on my history of putting the cart before the horse in a number of sub-assemblies on this project and I really HATE do-overs.

Any thoughts would be greatly appreciated!

Thanks, Tinkerman
 
While I've not tried it the other way, I think it will be easier if you mount the dash first, and then deal with the instrument panel.

In fact, I probably would have mounted the dash before wiring the panel, but hopefully the panel will fit through the hole

Dick, I have to agree that mounting the fascia (dash) first is IMO the better approach. I covered all of the vynide with easy release painter's tape to avoid damage. We left all of the securing hardware, fasteners, etc fairly loose so we could remove the fascia quickly if necessary.

Cheers,

Frank
 
I just did mine a few weeks ago. I put the dash in first. I had wired the cluster piece before I tried to put it into the dash. I had numbered the harness wires when I disconnected them. I put a corresponding number on a short piece of wire attached to the gauge or connection on the cluster. Anyway I used some masking tape to loosely attach the cluster to the dash. I then wired it all up without too many issues. I will suggest that the two connections with several wires going into the same connector will be better connected by using a wire nut and a short piece of wire. Putting only a single wire into the connector on the instrument cluster.

Put the Dash in first,then instrument cluster but what about the heater? If its not in already,put the heater before the dash.

Marvin, the heater is in. Gordon, I find two grommet holes in the center of the upper edge of the scuttle panel. One directly behind the other. Are these the grommet holes you are talking about? I would have no trouble getting to either one of them at this point. I can see it would be almost impossible once the dash and cluster are installed. I really appreciate you pointing that out to me, because I would have missed it.

Thanks, Dick
 
Yes Dick, those are the holes the wire for the vent pull go thru. You have already guessed how I know.....I missed it the first time!

The value of the forum are folks like you Gordon! Thanks very much, Dick
 
Hi Dick make sure you put in the defroster vents when you do the dash. I found that cleaning the threads on the studs that hold the dash make it easier also.

Thanks Steve, good point.
