Volvo 2-Speed Cooling Fan
Relay Connectors 58 Series Connectors and Terminals | |||
![]() |
Here are the correct sealed connectors used by Volvo for the Volvo
2-Speed Cooling Fan Relay found in 1990s
850 and 900 series models. These connectors are
WEATHER SEALED by an internal o-ring in the relay port and a rear cable
seal
that is inserted into the back of the connector
during assembly. So if you're
making repairs or if you're using a Volvo 2-speed
relay on another project, the correct
matching connectors can be found below. |
||
![]() |
2-Pole Female Connector
for speed #1 and #2 power output. This connector uses special large 9.5 mm female terminals. These special crimp terminals are designed for up to 10 gauge cable. Terminal amp rating: 40 to 60A using 10 or 12 gauge cable. Cable Seals: For a sealed connector, you should use silicone seals in the connector. BROWN seals or GRAY seals are available. The seal may be crimped to the terminal at the insulation support tangs. Rear Cover: The rear cover snaps into place to ensure the connector stays secure (for 2-pole housing only). |
||
![]() |
1-Pole Female Connector
for primary voltage power input. It also uses the
same special large 9.5 mm female terminals. These special crimp terminals are designed for up to 10 gauge cable. Terminal amp rating: 40 to 60A using 10 or 12 gauge cable. This FEMALE connector is also used in other locations under the hood of 850 and 960 models (main engine harness power connector), where it mates to the same style MALE connector shown below. Cable Seal: For a sealed connector, you should use a silicone seal in the connector. BROWN seals or GRAY seals are available. The seal may be crimped to the terminal at the insulation support tangs. |
||
![]() |
1-Pole MALE Connector.
NOTE: This connector is NOT used with a fan relay. It's used in other locations under the hood of 850 and 960 models, mostly for the main engine harness power supply. This connector is featured here because it MATES to the FEMALE connector shown above, which is also used in other places and models. The special crimp terminal is designed for up to 10 gauge cable. Terminal amp rating: 40 to 60A using 10 or 12 gauge cable. Cable Seal: For a sealed connector, you should use a silicone seal in the connector. The shown BROWN seals or GRAY seals are available. The seal may be crimped to the terminal at the insulation support tangs. |

Overcrimps for Large Wire |
SMALL OVERCRIMP PIC ![]() LARGE OVERCRIMP ![]() |
OVERCRIMPS
for
using Oversized Wire on Undersized Terminals Hard to find open barrel terminal OVERCRIMPS in two sizes: Small and Large. For use when your wire is a bit oversized for the terminal. In an ideal world, you would simply find a terminal that accepts larger wire. Try that with 8 or 10 GA wire on most available terminals. Sometimes the fit just isn't good enough. Adding one of these overcrimps can be a life saver. Overcrimps will not fit FLAG style terminals.

Terminal
Blocks NO LONGER AVAILABLE HERE |
![]() |
Eaton Bussmann terminal blocks like
these can come in handy if you want to tidy up your
wires. These terminal blocks are considered BARRIER type, because there is a defined barrier between each row. So this means it's possible to use one block for distribution to multiple circuits. Or it can be set up as an all-in-one common bus block. |
||||||||
![]() |
I used some of these
when I re-wired my dash in my 242 Turbo. In this photo, I used one 8-row
block to consolidate all dash grounds from gauges, relays, radio
and the AC system into one central location, instead
of the way Volvo did it by adding separate ground
points all over in different places. You can see that proj ect here: https://www.240turbo.com/classicair.html#terminalblocks. |
