2 plastic 5/8" outlets at the same end and close together which exit the heater on the r/h side.
The later HIF38 1275 and single point cars had a change point where the plastic outlets exited on the l/h. This is a JEF10005. These units take 5/8" heater hose, therefore on cars pre 1989 where the pipe work is still 1/2" you will need to fit 5/8" hose pipe with a reducer MOC210 and then 1/2" hose as required. The plastic outlets are on the new matrix but available as JEP10007MS repair kit if required.
