Jerome:
The relay that you identify with the part# is close to the part # specified for
Series I and II overdrive relay ( Supposed to be #33213A), so I suspect yours
is a later version of the same thing. A different relay is used for series III
onward(#33199E)
The horn relay is #33209 and is labelled "early cars only" as to application
(probably series I and II) The proper horns are 725 Low and High "Clear
Hooters"(up to series III).
I think you could probably substitute any relay for the horn relay, but
probably because of the heavier current drain of the
overdrive solenoid, you should assume that the overdrive relay is heavier duty.
Testing the relay is fairly simple. Just connect power to w1 and w2 and the
relay should operate. With power on, hook your ohmmeter to c1 and c2 on lowest
scale and it should read zero resistance. (some resistance indicates dirty
points and you should open up the relay and file them).
The location you describe is where my horn relay is (early Series I). I don't
know where the overdrive relay is located, since I don't have one, but I think
Terry McKitrick does. (BTW,the likely reason your horn switch was on the dash
was because lack of a horn relay had caused heavy sparking in your normal
(steering wheel) horn button).
