Tom in Austin

The very handy fuse and relay chart by 928 Specialists shows a different part number for the EZK relay (928.615.203.00) than the LH, Fuel Pump, and Ignition. The last three are all 141.951.253.B, which I believe we refer to as "53b"s.

The description of the EZK relay mentions "w/Fuse Tester", is that why it has a distinct Porsche number, and maybe otherwise is just a 53b like the others mentioned?

Last question, what's the best way to safely remove these guys? Tried a little careful pulling and wiggling and they seem to be pretty tightly seated. Is there a particular tool or technique that works well?

You are correct that the EZK relay on your car is the same in function as a normal "53" relay, just the the fuse tester funtion added.

So for testing, you can swop it for a known good "53". Note that the fuse tester only works with that special relay in in the EZK position. IIRC .

People on RL have reprorted using paint can remover tools to remove relays, but you MUST disconnect battery ground first, otherwise you may short out the relay pins.....

Tom, Roger has a real nifty tool he sells for relay removal.

There are a couple threads on tricks of removal w/pics of other tools. I've destroyed more relays than I've saved. the tool pictured is not great, but is prob the best available; what you need is something that can grab under the relay, hence the paint can opener. I've used a combination of the pinchers and then inserted a long zip fastener under and around the relay in order to pull on it from below. Whatever you use, add strong tilt sidways rotating w/360° motion and keep rotating.

Glad the charts helped!

We sold the OTC Relay Removal Tool as well as the Factory Tool (9235) for years. The OTC is a better built stronger tool and costs 25% of the Factoy Tool.

Part # is OTC4493 - You can walk in and get them at almost any Auto parts store like Advance Auto etc for $15, or online for $10.

The Fuse tester is interchangeable with any '53 relay for the basic relay function - the fuse tester portion will work with any relay base where the relay 30 and 85 are permanent connections to Battery+ and Ground respectively. Not all are. In the case of relay connected differently the fuse tester may only be avtivated when the relay or assocoiated switches are activated (e.g. ignition for some)...or not at all - not ideal.

So it will work in the EZK & backup lamp(AT) posistions and some others by year...

With the 53B being so cheap we recommend changing them all especially on the later cars where a number are used.
We also have a handy “ get you home kit” – Relay pliers, 53B relays x 2, Fuses (late and early style depending on MY) and a jumper for the fuel pump relay.

AO figured out a while back that those free pain can opener tool work well for gett these out... just make sure to disconnet the battery first.

If you do buy a relay puller, make sure you get the kind that grab all the way behind the relays and not just squeeze the sides.
