Glow plug issues
I have searched and still cant find an anwer. I am having problems with cold starting so I decided the 20 year old beast needed help. I bought some new beru glowplugs and a new gpc. I wired my gpc up first and now it wont work, I wired it the exact same as the old one. help. I am going to put in the glowplugs once I get this gpc figured out. I bought 16 glowplugs from autozone for 16 cents!Also they new glowplugs have the bullet typr attachments. but these beru have the clip on type attachments. how do I convert them?

It sounds like the beru glow plugs you purchased are ZD1A (Spade connector) for 83 -86 6.9L engines. Someone can correct me but I believe your 87 6.9L should use the ZD9 (bullet connector). You will have to tell them that you are wanting the ZD9 motorcraft glow plug specifically, don't let them try to cross reference to their Autolite glow plug or any other brand.
If you can't find the ZD9's at your local AZone you could check out ebay. Search on Motorcraft glow plugs.

The glow plugs you got are the bullet connector, which are the new style if I am reading you right.
Your engine should have used that type glow plug.
I have never tried the butt connector, but I have seen several times that others have used them if you find the right size.
For the price you gave, I would use them.

Two options,
Make a jumper with a male bullet connector on one end and a 1/4" female spade connector on the other end.
or
Cut the bullet connectors off and replace with female spade connectors.
I would probably go the first route, that makes it easy to go back later.

On my 1984 F250, I installed a solid state glow plug controller retrofit kit (part No. 1809443C96, cost was $ 271 at International Harvester dealer) in January 1995.
The kit came with new everything needed such as, wiring harness, glow plugs, detailed instructions etc.
It has worked flawless, I have lost only one glowplug in 13 years of use.

You cannot use the spade connector GPs with the solid state controller, so don't even bother trying. The systems are completely different.........the ZD 9 are PTC GPs..... positive temperature coefficient......
IH number for ZD9............ IH 1819649C1
