The 94-95 models came with R134a. So hook up your gauge set low pressure blue to fitting on POA valve in front of engine and red to high pressure fitting near receiver dryer under plastic cover behind false firewall.
With engine running and a/c engaged look for 35-40 psi on LP Gauge and 150-250 0n HP gauge. Radiator cooling fan should cut on about 200-215psi on HP gauge. If LP reading higher than 40-45 you probably need some freon.
