1970 Cougar - Ignition Switch question

Recommended Posts

The car = 1970 Cougar, Base model, 351C 4v, 4 speed transmission. Approx. 200 miles on engine rebuild. 

The only modification is a Pertronix. It still has the stock coil.

 

I've been thoroughly scouring the internet for answers to my question and I have found 99% of the answers on Mustang forums.

For sakes of typing here is a link to my post on the Cougar forum detailing my problem: http://www.mercurycougar.net/forums/showthread.php?119738-No-crank-from-ignition-Will-crank-from-solenoid

My MAIN question is: In all of my searches for a 70 ignition switch replacement I have found that one for a 71 will work BUT, no one has posted a final answer on this. Can a switch for a 1971 Mustang work for a replacement for a 1970? IE: Number of wires match? I know I have to splice the pigtail from my old one on to the new one but do the wires match and does it actually work?

 

I know it's a Cougar but take the body off and it's basically a Mustang so I was hoping for a little forgiveness.. :(

Don't get why you want a 71 switch? 70 cougars & mustangs use the same switch, same lower dash, steering column, pedals & components.

It's due to the following:

No aftermarket column available with the key in the column, West Coast Classic Cougar being "out of stock" for an OEM part that costs too much ($115 compared to $20 something), to name a couple.

From a wiring point of view, the Mustang 70 and 71 ignition switch plug is identical.  Since Cougars rarely deviate from standard Mustang items when there's no reason to change, I suspect the 70 and 71 Cougar ignition switches follow the Mustang paradigm.  Won't swear to it, but highly suspect it.

Whew! This is what I was looking for. A confirmation about the wires themselves on the 71 switch. I don't care if the wire colors are different as long as the number of wires is the same.

 

Anyone actually use a 71 switch in a 70 (or close) and have had good results?

 

Thank You!!

Paul

Nope, I was wrong.  That's what I get by going from memory; sorry 'bout that.  The 71 and 72 ignition plugs are the same; 68 and 69 are the same, but 1970 is unique to that year.  I do not have a 1971 Cougar underdash in stock.  The 1970 Cougar ignition plug is the same as the 70 Mustang.

ummm...$115.00 doesn't seem like too much to me for a very rare part like that, and I for one would gladly pay that if I needed one and would also be extremely grateful to whomever had it for sale.
