Datsun 1200, unlike the Datsun 1000, was designed with air conditioning in mind. However, it was still a dealer-installed add-on option and so varied by country and region. In April 1978 it became a factory option for Japanese market Sunny Truck. The interior cooler protrudes into the passenger legroom and precludes using a package tray.

Wiring

Since B110 A/C is fairly rare, you can source most of the parts from a B210 or B310. Only the interior vent setup is needed for a B110. They are fairly common on late model B122 Sunny Trucks.

Compressor

The compressor pump bolts to the engine and is driven by a v-belt

Crankshaft pulley double belt

Engine Brackets

Various types were used. Early A12 and late A12 brackets differ.

Dealer item

From USA catalog:

21060-H1001 FAN-COOLING A12 (standard B110 fan)

B122 Sunny Truck Kit

This kit is beautiful and easy to install. Unfortunately the interior cooler unit is bulky and protrudes farther into the passenger legroom than other types.
