Do they not come with moulded plugs? 

No just two wires with connectors.

you use the old plugs from original pumps.

i think wiring diagram says brown as earth.

but the old wires look black and blue!

Here you go Art. Front washer +ve is LG/B, rear washer +ve is LG.

Are they non OEM replacements? 
Just use a multimeter on 12vdc on the plug from the body harness, negative to body ground and one of the two will give you 12v when switched on. 
IIRC the one towards to centre of the car with the larger plug is the front, the smaller plug to the side is the rear. There is also a smaller one for the float switch. 

Should be very straightforward. 

All done no leaks & both pumps working.

thank you for wiring advice.

Out of interest Art, what pumps did you use? 

I bought them from CARID.com

from US cost is cheap but postage  expensive.

Cost is about £12 each.

i bought two and cost £150 with postage.

Trico- spray washer pump $11.30  says it fits 300zx 1984-1996

i had to hacksaw the plastic part off & cut the connection down.

then I soldered the wires onto the connectors & covered them.

both fitted & working!

£150 with post for two $12 parts? Surely that’s a typo?
