Oil pressure gauge with single terminal warning light?
Chrysler produced a fitting for vehicles using both indicator light switch and pressure gauge sending unit for the small block V-8s and 225 slant six in the late 1970s.
The fittings are shown in the following diagram. Left to right: V-8 without vacuum advance, #3747433, V-8 with vacuum advance, #3747434, and 225, #3747432:
3747433:
3747433 fitting with original Chrysler Introl 3488609 sending unit and 2298882 switch:
3747433 fitting with original Chrysler Introl 3488609 sending unit and 3747431 combination choke control and pressure switch:
3747433 fitting with common aftermarket sending unit and switch:
The sending unit and switch can be in either fitting port. For A-bodies, F/M/J-bodies, and 1970-prior B-bodies, the arrangement as shown in the diagram fits better, depending on the distributor setup. In later B-bodies, C-bodies, R-bodies, and trucks, arrangement in the other picture, or the diagram, can fit okay. It is a little cramped for space either way though. On a big block, either arrangement can work, depending on the proximity to the firewall.
If using 3747433 with a vacuum advance distributor on a small block as arranged in the actual images, the sending unit can interfere with the vacuum canister. One or two 45 degree adapters.or a 90 degree adapter, can remedy this.
