Wanted- pre glow relay

[smokeswagen]

I need a pre-glow relay (aka "engine control module") for an '86 740TD. This is NOT the large black box [80A glow plug relay] on the front of left side wheelhouse, but rather the small tomato-red plastic relay next to it. Volvo #s are "898350 & 1362 422"
Power rating is "12V/0.7A". It has 4 wires in a square plug and a single black ground on a spade connection running out of the bottom of it- they go to fuse 13, the starter, rear coolant sensor, and pre-glow indicator light. Function is to short-time the glow plugs when the engine is warm.

Mine's fried and i can't seem to locate one online- will pay reasonable price for new or functioning used one will or trade-
injector pump core for 740td w/auto (both sol's good)
ZF 4hp22 rebuildable core (no converter)
Leycock o/d unit- rebuilable core (w/good solenoid)
intact b26 w/ Asian Warner still attached (ran when pulled)

I'm in the Northeast, so if you'd rather take a part in trade instead of $,
I hope you are too. PM if interested.

Regards

'84 245d n/a w/M46
'86 745td w/ 4HP22
