1st Generation 1964 1/2 - 1973 - Questions & general discussions that apply to a specific year => 1966 Mustang => Topic started by: KevinK on December 29, 2021, 01:30:16 PM

Is the 66 289 SJ negative battery cable mounted to the engine block same as the 67? I found this one mounted on the front of the cylinder head. I would assume the alternator ground is in the same place.
Lastly, is the coil mounted to the right side of the intake with TE, AC and PS? I found this one on the left side cylinder head.
I have to assume this engine has been removed and things like the heads replaced. I doubt anything is correct.

The battery ground (aka negative) and the alternator ground are attached by a bolt (or a stud with a hex head drive in the middle, for AT cars, no known Ford part number, I used "UNK-02" in the spreadsheets), 20350-S36, and a lock washer, 34943-S36, to the a 289 block under the alternator.
It should be the same as 1967 Mustangs. The "stud" was introduced for early 1966 Ford 289 engines.
Lastly, is the coil mounted to the right side of the intake with TE, AC and PS? I found this one on the left side cylinder head.
On my 66 San Jose Hardtop with smog and PS, the coil was mounted on the RH side to the intake manifold. To be truthful, it appears that the coil went anywhere it would fit on a car with multiple options.

Thanks Jim.

Just to provide you with the best and most complete answer as well as possibly some addition details that may help you we would need to know when and where the car was built as well as if the car was an automatic also

I've found the hex drive stud on automatic cars as there was a holder clamp there for the metal cooling lines.

+1 Just was trying to confirm so I could post some examples if the car in question was so equipped :)

It should look like this. Purchased the Plasti-Dip at Home Depot for the coolant line holder. I used a little gun blue on the clamp before I dipped it.

The bracket is identified in Ford Car Parts (aka MPC) Illustrated section, A71, page 6, as base number 7C008. I have not been able to find any further documentation.

I agree. I dipped the bracket a couple of times to get a thicker layer on it. Instead of gun blue, I use the Eastwood metal blackening dip before phosphating. The bracket, 7C008, is available from most Mustang parts sellers.

Automatic car. I will get the vin tomorrow.
I seems the motor has been out and apart sometime ago. No signs of the stud or bracket for the lines. It would certainly make it easier to install. I know the shop who recently put a new carb on it lost most of the original hardware. They were also the ones who stated it had 6 cylinder steering linkage. I'm sure the shop who had the engine out lost half of that stuff too. The more I look, the more I find. I noticed 1 bolt was halfway out on the cross member. Lots of poor repairs the the engine harness too.
Just helping out a friend.

Not sure how early this one is.
Thanks for the info.

You need the stud that I could not find a part number for, and I identified as "UNK02". It has 7/16-14 threads at both ends. Stud 380808-Sxx is used on the 200 I-6 only, and has 3/16-16 at the end that goes into the block, 7/16-14 for the cables. Apparently, the I-6 block is tapped for 3/8/16 threads for battery ground, the 289 block is tapped for 7/16-14.

Thanks and sorry for the delay. Been real busy with things :)
I could picture the photo I wanted to post but could not remember exactly where it was in my Library
Found it with a search of this site and the thread below that has one or more pictures of the same area from different angles

Wow, now that covers it and a few more questions. Thank you.
-
having a difficult time identifying specification and then probably finding bolt to attach ground wire from battery to the front right(passenger side) of engine block.
Any help or spec out here? Someone have one perhaps?
similar question on correct coarse threaded screw with hex top to attach ground wire to firewall.
Thanks much
-
Should be in the Ford assembly manual and then cross-reference to Jim's fastener spreadsheet in the library section. Or, can cross-reference the fastener ID to the AMK guide to fasteners.
-
To add if after identifying by the method Charles suggested the bolts by size and thread you can find them in misc bolts that may have come from your car or other. If not then AMK sells them .

The hardware required depends on year (I assume 1966), plant (it seems San Jose may have done things different), date of production (a running change), engine and transmission.

This screw is standard, and is documented in the 1966 Mustang Electrical Assembly Manual (AM0013 pg 15 and 36 - same hardware, different engines).
The hardware spreadsheets in the library for 64 thru 66, have the required items listed by application - "WIRING GND,BATTERY-ENG,***(eng type) and "WIRING GND,ENGINE-FIREWALL@FIREWALL".
I recommend you get a set of the 1966 Mustang Assembly Manuals, plus the 1964-65 Chassis and 1965-65 Weld and sealant. They answer questions you haven't thought of yet.

Using the search feature and the words "66 Ground cable" I found this thread will be merging

Jim's spreadsheet lists the battery (neg) to block bolt as a 20350-S36.
The 66 Assy Manual (see attach) lists the bolt as an S8. The 67 Assy Manual does not show this bolt (see if you can find it for a 289).
The 67 390 lists the bolt as S8 in both the s/s and the Assy Manual.
Since resources do not agree, which is it on an unrestored car? My 65 FB engine shows no sign of the dichromate. This is a bit of an oddball bolt in its length and lack of markings so I don't believe it has been replaced.

Did you take the time to see what the reference document I used for this entry is? I list them all in the right hand column of the spreadsheet. The reference to 20350-S36 is in the "1966 Mustang Electrical Manual" (AM0013) pg 35.
You can thank me later.

And the picture shown in my previous post of "20350-S8" is from the "1965 Mustang Electrical Manual" Page E5-8601-5, which I should have noted.
I didn't have the 66 handy at the time of my previous post but it does show the 66 bolt as "20350-S36."
So 65 is S8, 66 is S36 and the same pic is not found in my copy of the 67 Electrical Assy Manual.

Actually, it is. Bolt 20350-S36 (along with lock washer 34393-S36) are on page 33 of the "1967 Mustang Electrical Manual" (AM0018).
