I have just fitted a Glow Plug Timer relay to my 2.5 NAD, it looked as though it was going to be a right pain, instead it turned out to be almost straight forward !!
I bought a glow plug Timer relay of ebay quite cheap and the fitted as follows

PIN 1 - I connected this via 10mm cable direct to the Battery Positive (6mm is Minimum that you need)
PIN 2 - I used 10mm cable and connected this to Glow Plug 4 (nearest Bulkhead)
PIN 6 - Connect this to the Chassis Ground
PIN 4 - Connect to any White Wire in Wiring loom, I fed via Bulkhead into Dash panel and connected in there.
I left all of the original wiring for the glow plugs in situ, so this also provides a back up way of using the glow plugs should the timer fail, also this also back feeds the glow plug light on the dash panel
here are a couple of Images of the relay all wired up and in situ -

have to remember this for when i do mine
-
Looks as though we have similar vehicles, my was a hard top like yours and I have often thought we both had the same vehicle !, I am only in Rushden, your more than welcome to pop over and see what I done to mine

got mine of ebay about 2 years ago seller said needs little work for mot got it home and a sive had less holes so ive had to replace the chassis and rebuild it up just waiting for better weather to carry on brought the disco for the engine to go into it also of ebay but this time looks like it might b staying on the road for at least 1 more year the pics in my gallery are the ones of ebay makes the 90 look a lot better than it was and the disco was dirty so think most looked and moved on the wife cleaned it inside and out and only needs a little welding so far
-
i fell for the same trick as you and i had to re chassis mine aswell . im very interested in the relay though does it work ok how long does it stay on for?
-
Relay stays on for about 10secs, at present the 90 needs 2 lots of glow plugs, possibly 3 goes, depends on how cold it is when I get in it !
-
mine was well ruff to start so i tryed giving it 10 seconds then turn it over then drop the key back to the glow plug position and now it starts first time every time . can you do that with a relay ? :huh:
-
The relay is temperature sensitive (which is why it's high up at the back of the engine bay and on the exhaust side I guess) and mine has the following (rough - from memory only) timings:
Mild: At room temp in the house: about 7 seconds.
Warm: In a previously running engine bay: about 3 seconds.
Cold: Been in the freezer for ten minutes: about 13 seconds.
Also: I think that it will run the heaters anyway while the starter is turning.
Also (II): If you turn off the ignition and then turn it on again it appears to run the heaters again, but for a shorter time (presumably due to internal heating?)
HTH
