16P or 18P? A Kia Rio window-switch comparison for importers
The Rio references SAP-WS002 and SAP-WS003 show different connector notes and OE lists. Use those differences before requesting a bulk price.
A buyer looking for a Rio front-left master switch may encounter SAP-WS002 and SAP-WS003 in the same catalog section. WS002 lists 93570-1W155 and 93570-1W150 with 16P; WS003 lists 93570-1W157 with 18P. The printed vehicle descriptions are references, not proof that either unit fits a particular car.
Count what is actually on the original
Ask for the rear connector photo, not just the switch face. Record the original part number and the observed pin count separately; if the connector has more than one block, describe each block instead of supplying a single total.
Keep the suffixes intact
The 1W150, 1W155 and 1W157 endings are not interchangeable shorthand. Preserve every digit in the RFQ and require the supplier to name the exact proposed SKU. If a seller proposes a different OE, request a documented reason and compare the physical evidence before approval.
Avoid a mixed carton surprise
For a trial order, keep 16P and 18P on separate purchase lines and labels. State whether samples are needed and which original photo each sample should be checked against.
Purchasing guidance, not installation or diagnostic instructions. Confirm compatibility and specifications with the supplier and a qualified technician.
